When the server is very busy with many client connections, client request threads may repeatedly conflict with each other for access to low-level system resources. Flow control provides a coarser level of granularity for synchronizing access to system resources by request threads. When enabled, flow control can improve performance by replacing multiple, serial choke points in the request processing sequence with a single choke point. Flow control can be enabled separately for HTTP and IIOP clients. For more information, see “Flow control” in Chapter 2, “Server Tuning,” in the EAServer Performance and Tuning Guide.
