Reduces the world-save freeze window from ~740ms to ~78ms (measured on a synthetic 10M-entity / 1.7GB world, 24 cores, through the real pipeline classes) by removing the per-entity handoff between the game loop and the serialization workers, fixing how large indivisible payloads are scheduled, rewriting the BufferWriter hot path, removing per-entity placement state entirely, and finally replacing the global serialized-types tracking with a per-file type table (idx v4) that also shrinks idx files by ~21% and speeds the background write phase. The pipeline has also been validated end-to-end on live-copy worlds in the multi-million-entity range, where the freeze is drain-bound (real `Serialize()` costs far more CPU per byte than synthetic writes) — the same structural wins hold, and entity/file round-trips are byte-clean across both load paths.
## The problem
The freeze window is `max(main-thread handoff, slowest worker drain)`:
1. **The producer was the bottleneck.** The main thread round-robined every entity through per-worker `ConcurrentQueue`s — two interlocked ops per entity, ~740ms of freeze floor at 10M entities before any serialization happened.
2. **Round-robin distributes count, not cost.** "Deep" systems (50MB generic persistence blobs) and "thick" entities (100K-item storage keys) landed on arbitrary workers, producing lopsided drain times on large worlds.
3. **Worst-case scheduling.** `GenericEntityPersistence.Serialize` pushed its self-payload *after* all entities, and generic persistences sort last in the registry — so the biggest indivisible blobs started serializing at the very end, extending the freeze by their entire duration.
## The fix
**Commit 1 — chunked handoff + LPT scheduling + heap pre-sizing:**
- Pooled 4096-entity chunks published to one shared queue; workers pull chunks and load-balance dynamically (a worker busy with a thick entity simply takes fewer chunks).
- `Persistence.SerializeAll` pushes systems largest-first (LPT) using the previous save's payload size (or loaded file size on first boot); self-payloads get dedicated single-entity chunks so they overlap the entity stream instead of ending it.
- Worker heaps pre-size from the loaded save's `.bin` totals, eliminating copy-on-grow inside the first save's freeze.
- `SpinWait` backoff in the drain loop (never `Sleep(1)`), per-worker balance stats logged in debug builds (the call site is compiled out of Release), 1MB snapshot write buffer.
**Commit 2 — workers iterate the dictionaries directly + main thread joins the drain:**
- `GenericEntityPersistence` publishes 4096-slot ranges over its dictionary's backing entries array; workers serialize occupied slots (`value != null`) directly through a `ShadowEntry<TValue>` struct mirroring the runtime's private `Entry` layout. Safe because the dictionary is frozen during `Saving` (mutations divert to the pending safety queues).
- The layout is **proven at startup before any code reads through it**: validation measures the true `Entry` stride via precise allocation accounting (guaranteeing all shadow reads are in-bounds), then verifies every key/value of a churned, resized, freelist-exercised dictionary — reading value slots as raw pointer bits only, never materializing a managed reference until the layout is proven. If a future runtime changes `Dictionary` internals, validation fails with a logged warning and saves fall back to the (fully maintained) enumerate-and-push path.
- The main thread joins the drain via an inline worker after publishing, instead of idling — worth a full worker share, proportionally more on low-core hosts.
**Commit 3 — 2.2x faster BufferWriter write path, single-pass short strings:**
- PGO already devirtualizes and inlines every `IGenericWriter.Write` callsite (interface vs concrete measured identical) — the real per-write cost was the non-inlinable `Index` setter (range-check throw path + per-write high-water tracking) plus span bounds checks. Writes now reserve capacity once, then do an unaligned store through a ref with a raw index increment; the high-water mark folds at Seek/Resize instead of per write.
- Class-level implementations of the hottest default interface methods keep nested writes inlined (a DIM re-dispatches on `this` even at a devirtualized callsite).
- Strings of 85 chars or fewer encode once into a stack scratch instead of walking the string twice (`GetByteCount` + `GetBytes`). Byte output is identical.
- Measured: 34.4 → 15.7 ns/entity on a generated-style write mix; end-to-end freeze ~99ms → ~74-82ms.
**Commit 4 — branch-free fallback push loop:**
- A bare `foreach { PushToCache(entity); }` runs at 2.3ns/entity; the same loop carrying a per-entity heavy-check runs 2.3x slower — the cost is the fatter loop body defeating tight-loop codegen. Entity-level >1MB payloads are rare enough to ride in shared chunks; system self-payloads (the large ones) are still explicitly scheduled largest-first.
**Commit 5 — drop the 9-byte per-entity placement state; snapshots write from worker segment logs:**
- Every `ISerializable` carried `SerializedThread/SerializedPosition/SerializedLength` so `WriteSnapshot` could gather each entity's bytes from the worker heaps in dictionary order. But the idx records absolute positions — bin order is free — so the snapshot is now written in worker-heap order and the join inverts: workers log segments (owner, slot range, heap start) plus one length per record as they serialize; positions are implicit because a worker's writes are contiguous, and identity comes from re-walking the same snapshot slots in the same order (stable until `PostWorldSave`).
- Chunks are persistence-homogeneous (the partial chunk publishes at each `SerializeAll` boundary) so segments route to files by owner with zero per-entity state. Self-payloads keep placement as three private fields on the handful of persistence instances.
- Net: 9 bytes (plus padding) of resident state removed from every item, mobile, guild, and account on every shard; three interface-property stores per entity leave the drain hot path (stamping dirtied one cache line per entity mid-freeze — the lengths log is one sequential stream); each segment's bytes hit the bin as a single span write instead of one copy per entity, speeding the background write phase; and `IGenericSerializable` shrinks to just `Serialize(IGenericWriter)`. Transient cost: ~4 bytes per entity in pooled per-worker logs, released after each write. The save format was unchanged at this point (idx v3, same loader); the v4 bump comes later in the branch.
**Commit 6 — staged file writes replace memory-mapped snapshot writing:**
- `MemoryMapFileWriter` is removed. `FileBufferWriter` composes through the full `BufferWriter` raw write path into a pooled staging block that drains to the file as large sequential positional writes (`RandomAccess.Write`); seeks flush the block and move the file offset, so backwards patches (the idx entity count) become small positional writes.
- Memory-mapped composition paid a soft page fault on every composed page plus unpredictable dirty-section teardown stalls at dispose — measured ~4x slower end-to-end than staged writes at snapshot sizes.
**Commits 7–11 — idx v4: per-file type table replaces SerializedTypes.db and all runtime type tracking:**
- Previously every `Write(Type)` from every worker enqueued into a shared `ConcurrentQueue<Type>` during the freeze (interlocked writes on a shared cache line, millions of mostly-duplicate entries), the background phase drained and deduped it all into a `HashSet`, and the snapshot recomputed `xxHash64(Type.FullName)` once per entity record (~5.4M redundant hashes per save on a large world) to write 9-byte tag+hash idx records plus a global `SerializedTypes.db`.
- The db's only real job was diagnostics: the string name behind "Type `<X>` was not found. Delete all of those types?" during idx loading. That map now lives in the idx itself: each `GenericEntityPersistence<T>` keeps an insertion-ordered `Type -> ushort` table, hydrated at `AddEntity` and on every deserialize path — one dictionary `TryAdd` per entity add on the game thread, amortized across gameplay, and provably immutable while the background writer reads it (adds divert to the pending queues during saves).
- idx v4 layout: the table (names only) is written before the records; records reference it by 2-byte index, shrinking from 33 to 26 bytes (−21%). The loader resolves each table name **once** (`FindTypeByHash(ComputeHash64(name))` — semantically identical to v3 resolution, `TypeAlias` included) into a constructor array, and each record becomes an array index instead of an 8-byte hash read plus dictionary probe. The unresolved-type prompt now surfaces once per type, with the name.
- Deleted outright: `World.SerializedTypes`, the drain/dedupe pass in `WriteFiles`, `BufferWriter`'s type tracking (its `Write(Type)` is now pure — payload format unchanged: tag byte + xxHash64), `FileBufferWriter`'s typeSet parameter, `Persistence.WriteSerializedTypesSnapshot`, and the adhoc db write. SerializedTypes.db is no longer produced.
- **Backward compatibility:** v0–v3 saves (including their SerializedTypes.db and legacy tdb files) load exactly as before, and every legacy load path hydrates the new table so the first v4 save after an upgrade is complete. Stale db files in existing save folders are simply ignored. Verified live: a v3 save boots, saves as v4 (Items.idx −20.2% on a dev world), and reloads with identical entity counts.
## Measured (synthetic 10M entities / 1.7GB, 64+64+32MB system blobs, 24x 2MB thick entities, dense write profile, 24 cores)
| Metric | Before | After |
|---|---|---|
| Steady-state freeze | ~740 ms | **~78 ms** |
| Main-thread publish cost | ~740 ms | **~0.1 ms** |
| Steady-state allocations | 0 | 0 (by iter 2) |
| Worker byte-load spread | 2x | ~1.15x |
The freeze is now bound by pure serialize throughput (payload / cores).
## Tests
- 779 Server.Tests + 501 UOContent.Tests pass.
- New across the branch: chunk fill/flush/owner-boundary tests, pool reuse/clear tests, an end-to-end multi-worker drain through the real wake/push/flush/pause protocol, a 50K-entry churn equivalence test for the shadow iteration re-walk (the exact pairing the snapshot writer relies on), byte-level BufferWriter output/position pins, `RuntimeLayoutIsSupported` so a silent fallback on a future runtime upgrade fails loudly in CI, and a full snapshot **round-trip test** that serializes 25K entities plus a self-payload through real workers, writes the idx/bin from the segment logs, and reloads them through the standard loader (now in v4 format).
- For idx v4 specifically: `FileBufferWriter` staging/drain/seek-patch and oversized-item tests, type-table registration tests, a hand-written v4 fixture proving an unresolvable type name skips only its own records through the console confirmation flow, and a hand-written **legacy v3 fixture** proving old saves still load and hydrate the type table for their next save.
## Trade-offs
- Chunk scheduling is nondeterministic, so worker heaps ratchet to each worker's max-ever draw rather than a fixed share. With slot ranges the balance is tight (~1.15x), so the effect is small; a shared slab pool remains an option if production shows retention creep.
- Entity-level heavy items inside slot ranges are serialized wherever they're encountered (no LPT for them); worst-case tail is one thick entity's serialize time (~ms). System self-payloads — the large ones — are still explicitly scheduled largest-first.
- Snapshot-write error granularity is per segment rather than per entity (heap-bounds bugs were the only thing the per-entity catch ever caught; idx metadata reads keep per-record granularity).
- idx v4 is a save-format version bump: old saves load unchanged through the preserved legacy paths, but saves written by this branch require this loader. Per-persistence type tables cap at 65,535 distinct entity types per boot (hard throw, orders of magnitude of headroom), and a type's table slot persists until restart even if its last entity is deleted — a few stale name entries per file, by design.
## Summary
Migrates the Old Guild System (pre-AOS guild stones) gumps from the legacy `Gump` class to `DynamicGump`, following the same pattern used for the Quest gump migration in #2416. All concrete gumps now have private constructors gated by static `DisplayTo` entry points (empty-gump rule), and `Singleton => true` is set across the board so reopening a sibling dialog automatically closes the previous one.
**Migrated gumps:**
- `GuildGump` - main guild dialog
- `GuildmasterGump` - guildmaster functions
- `GuildCharterGump` - charter and website display
- `GuildWarGump` - warfare status (kept as player-facing)
- `GuildWarAdminGump` - war menu (retained as player-facing - reachable from `GuildmasterGump`'s WAR button by guildmasters)
- `GuildChangeTypeGump` - Standard/Order/Chaos selection
**Abstract bases:** `GuildListGump` and `GuildMobileListGump` keep their shared list-rendering chrome inside a single concrete `BuildLayout` on the abstract class and expose a `protected abstract void BuildHeader(ref DynamicGumpBuilder builder)` hook for subclasses (replacing the old `Design()` override). This mirrors the abstract-base treatment used for the ML quest base in the quest-gump migration PR.
**Concrete subclasses migrated alongside the abstract bases:**
- `GuildListGump` subclasses: `GuildAcceptWarGump`, `GuildDeclarePeaceGump`, `GuildDeclareWarGump`, `GuildRejectWarGump`, `GuildRescindDeclarationGump`
- `GuildMobileListGump` subclasses: `DeclareFealtyGump`, `GrantGuildTitleGump`, `GuildAdminCandidatesGump`, `GuildCandidatesGump`, `GuildDismissGump`, `GuildRosterGump`
**Cliloc rule:** Every gump bakes per-instance dynamic content (guild names, member names, war declarations, candidate lists), which would defeat `StaticGump<T>` caching. Per the cliloc rule, all are `DynamicGump`.
**External callers updated:** the prompt files (`GuildAbbrvPrompt`, `GuildCharterPrompt`, `GuildDeclareWarPrompt`, `GuildNamePrompt`, `GuildTitlePrompt`, `GuildWebsitePrompt`), `RecruitTarget`, the `Guildstone` item, and the New Guild System `GuildInfoGump`'s Order/Chaos handler all now go through static `DisplayTo` entry points instead of `new XGump(...)`.
### Summary
- `GenericEntityPersistence` is now a type of `GenericPersistence`. This allows developers to serialize both entities and non-entities in the same system. 🎉
- Each `SerializationThreadWorker` now allocates 1MB of heap for serialization _permanently_. If more memory is needed, that thread will double it's memory, not to exceed increments of 64MB.
- Several bugs with serialization introduced with the pure MMF implementation have been fixed.
- `BinaryFileReader` has been added back. 🎉
- Adds `world.useMultithreadedSaves` to allow disabling threaded saves.
> [!IMPORTANT]
> **Developer Note**
> The split file serialization has been deprecated and is no longer used. We have effectively gone back to the same file writing we had before the pure MMF implementation.
### Summary
Updates the serialization strategy to use `MemoryMappedFile` instead of thick buffers. This has the benefit of being on-par with the current implementation (based on hardware/OS), however won't incur the double-memory issue.
> [!Important]
> **Developer Note**
> The `BinaryFileWriter` and `BinaryFileReader` has been removed in favor of `MemoryMapFileWriter` and `UnmanagedDataReader`
## Summary
### Changes
- Adds `[IgnoreDupe]` and `[SerializedIgnoreDupe]`
- Updates all _known_ classes that need the attribute. Some might be missing, please helps us find them!
- Adds `Item.Dupe()` command and encapsulates `CopyProperties` and `OnAfterDuped`. This is also overridable.
- Updates Dupe command to use the new logic.
- Fixes duping multiple kinds of objects that used to be outright broken.
### Bug Fixes
- Fixes issue with durability after duping
- Fixes issue with hue after duping
> [!Note]
> **Developer Note**
> Customizing how duping an item works now requires two steps:
> 1. Add `[IgnoreDupe]` or `[SerializedIgnoreDupe]` to the property/field
> 2. Add custom logic in an `OnAfterDuped` override
>
> When do you need to do this?
> *When the property being copied is not a primitive, and you need to manually deep-clone the contents of the property such as with Lists, Dictionaries, or sub classes.*
### Summary
Adds a generic entity persistence. This can be used to create new entity types that have a `Serial`.
Here is an example:
```cs
public class BOBEntries : GenericEntitySerialization<IBOBEntry>
{
public static void Configure()
{
Configure("BOBEntries");
}
}
```
The annotation tells the system what folder to serialize the entries to. The class/interface (`IBOBEntry`) is the root type that implements `ISerializable`.
## MAJOR CHANGE
Added a champion title system to facilitate the existing champion titles. This should make it easier to extend or create other related game content. Champion titles will be saved in a folder called _ChampionTitles_.
### Motivation
The motivation to refactor was two-folder, but mostly related to performance in two ways.
First, every player had a ChampionTitleInfo object with an array of ChamptionTitleInfo. We want to eliminate the need for this information unless a player actually uses it. This should save a considerable amount of memory.
Second, to facilitate the atrophy mechanic, the champion titles would run atrophy post-world save, adding to the time that the server is frozen. Eliminating this post-world save side effect unlocks our ability to further optimize the world save process since there are no direct side effects.
### Bugs fixed
- [X] Fixed titles getting cut off on the paperdoll
- [X] Fixed champion title not displaying overhead (OPL)

### Changes
* Implements an AfterSerialize method that is executed synchronously.
* Removes `BeforeSerialize` support since it was dangerous in its current implementation.
* Moves PlayerMobile kill/virtual decay to AfterSerialize.
* Adds kill decay to after Deserialize.
## Changes
* Improves type hashing by introducing xxHash3 (64bit)
* Removes individual `tdb` files in favor of a single `SerializedTypes.db` file. This file is only used to identify a type that is being deserialized, which doesn't exist.
* Adds duplicate type alias detection
* Adds `AssemblyHandler.FindTypeByHash`

## SerializedTypes.db
The serialized types file is used to get back the original name of a type in case it no longer exists in code. This can easily be necessary if a class is renamed in code and no `TypeAlias` is provided.
### Format
byte[4] - version
byte[4] - count
--array--
byte[8] - xxHash
byte[1] - flag, 0 - null, 1 - not null
byte[n] - Full class name in UTF8
### Example

## Benchmarks
Serialized 500 Type fields. The 8192bytes comes from the _ConcurrentQueue_ that would later be used for SerializedTypes.
Note that the queue is never cleared, so it's size grew considerably.
```cs
| Method | Mean | Error | StdDev | Allocated |
|--------------------- |---------:|---------:|---------:|----------:|
| BenchmarkXXHash | 18.44 us | 0.278 us | 0.260 us | 8192 B |
| BenchmarkTypeStrings | 25.09 us | 0.292 us | 0.259 us | - |
```
TODO:
* Add support in the Serialization Generator for `ReadType()` and `Write(Type)`
* Remove `SetTypeRef` from Serialization Generator
**Only one functional change**
* Fixes a bug in LogFactory where `Warning` is being logged as `Information`
Non-functional changes:
* Updates/Fixes copyright headers
* Removes namespace scopes for core files.
View with [whitespace off](https://github.com/modernuo/ModernUO/pull/1187/files?w=1).
* Adds `BeforeSerialized` for entities to handle cleanup.
* Adds `Created` and `LastSerialized` fields to all entities. While this is a big bloat, this will be necessary for identifying dangling references to other invalid entities.
* Changes formula for determining a valid reference to be _not null, not deleted, and reference's created date must be at or before the entities last serialized date_.
* Adds versioning to idx file and serializes `Created` and `LastSerialized`.
* Fixes Save Stats and also disables it by default.
- Adds `[ManualDirtyChecking]` for anyone that adds it themselves.
- Adds detection of `[Serializable]` and `[ManualDirtyChecking]` at startup to help identify scripts that need migration.
### Additions
- Automatically opts-out `Item/Mobile/Guild/Accounts` from dirty checking with a new property `UseDirtyChecking`
- Codegen now enables `UseDirtyChecking` via getter. This requires that the property is `virtual` for derived types.
### Fixes
- Fixes `EncodedInt` being broken
- Fixes issues with new custom serializable types that are not derived from Item/Mobile/etc.
- Removes double dirty checking.
### Example of a brand new serializable type that isn't an Item/Mobile/etc.
User created code:
```cs
using System;
namespace Server.Items

### Features
* Fully abstracts serialization by using compile-time attributes.
* Supports serializing the following:
- Primitives (integers, strings, etc)
- IP Addresses
- BigDecimal
- DateTime, Delta DateTimes
- TimeSpan
- Server.Race
- Server.Map
- Point2D, Point3D, Rect2D, Rect3D
- Existing/New `ISerializable` references
- Lists/Sets of serializable types
- Type with a `Serialize` method and constructor that takes an `IGenericReader`
* Supports forward-only migration
* Supports existing RunUO deserialization for older versions by changing to the following signature:
- `public void OldDeserialize(IGenericReader reader, int version)`
- Must remove deserializing the version since this is already done
* Supports serializing from private fields or custom made properties.
* Types do not require inheriting Item/Mobile. Code gen will fully create `ISerializable` information.
- This is not recommended yet, since it requires wiring to `Persistence` which will cause lots of unresolved symbol errors until code gen is built.
### Example
```cs
using System.Collections.Generic;
namespace Server.Items
{
[Serializable(1)]
public partial class TestItem1 : Item
{
[SerializableField(1)]
[SerializableFieldAttr("[CommandProperty(AccessLevel.Administrator)]")]
private List<Item> _someProperty;
private void Deserialize(IGenericReader reader, int version)
{
}
}
}
```
Generates this:
```cs
namespace Server.Items
{
public partial class TestItem1
{
#pragma warning disable 0414
private const int _version = 1;
#pragma warning restore 0414
[CommandProperty(AccessLevel.Administrator)]
public System.Collections.Generic.List<Server.Item> SomeProperty
{
get => _someProperty;
set
{
if (value != _someProperty)
{
((ISerializable)this).MarkDirty();
_someProperty = value;
}
}
}
public TestItem1(Serial serial) : base(serial)
{
}
public override void Serialize(IGenericWriter writer)
{
var savePosition = ((Server.ISerializable)this).SavePosition;
if (savePosition > -1)
{
writer.Seek(savePosition, System.IO.SeekOrigin.Begin);
return;
}
writer.WriteEncodedInt(_version);
writer.Write(_someProperty);
}
public override void Deserialize(IGenericReader reader)
{
var version = reader.ReadEncodedInt();
if (version < 1)
{
OldDeserialize(reader, version);
((Server.ISerializable)this).MarkDirty();
return;
}
SomeProperty = reader.ReadEntityList<Server.Item>();
}
}
