TsgcWebSocketServer_HTTPAPI › Properties › ThreadPoolSize
Number of worker threads serving the http.sys request queue through IOCP.
property ThreadPoolSize: Integer read FThreadPoolSize write FThreadPoolSize;32
Sets the size of the IOCP worker pool that dequeues requests from the http.sys kernel queue and dispatches them. The default of 32 is a good match for most workloads; 64 is the recommended upper bound — larger pools rarely help because http.sys itself scales with CPU count. When FineTune.OperatingMode is ompHighPerf, the total concurrent pre-posted receives equals ThreadPoolSize x FineTune.HighPerfAcceptsPerWorker. Must be set before activating the server.
