Server plugin for engine-level tuning and performance monitoring. It sets Unreal Engine console variables from its config and confirms with the engine that each one took (the shipped config tunes ARK's own garbage-collection schedule), can lower how often structures replicate, and reports the server's real tick rate, UObject counts, dino and structure counts, memory and network, on demand and in a rotating stats log, with every server stall logged by time and length. ServerPerformance.CVar reads or sets any console variable live, so values can be tried on a running server before they go into the config.

Status: in testing. The ASA version runs on the test server (garbage-collection settings measured on a Lost Colony live save); the ASE version has not run on a server yet.

Folder	Game	Server API (submodule)	Player key
ASA	ARK: Survival Ascended	AsaApi at ASA/extern/AsaApi	not used (no per-player data)
ASE	ARK: Survival Evolved	ArkServerApi (AseApi) at ASE/extern/AseApi	not used (no per-player data)

Each folder is a self-contained Visual Studio solution. Clone with submodules:

git clone --recurse-submodules https://github.com/bushome/ServerPerformance.git

or, in an existing clone:

git submodule update --init --recursive

The logic (src/PerfLogic.h), the tests and the configs are the same in both folders; only src/Main.cpp, src/EngineBridge.h and the project files differ by API. Differences in behaviour:

• Missing engine symbols. On ASA every engine function and field the plugin uses is looked up while it loads, so after a game update that removes one, AsaApi skips loading the plugin and logs the name (the server keeps running). On ASE a missing symbol switches off only the feature that needs it, with an error in the log.
• gc.TimeBetweenPurgingPendingKillObjects is a console variable on ASA (Unreal Engine 5). ASE's engine keeps it as an engine setting instead; the ASE build reads and writes that setting under the same name, so one config works for both.
• Structures.MinNetUpdateFrequency exists only on ASA; ASE ignores it.

Build and install steps are in each folder's README.
