Ice.TCP.Backlog=num

Specifies the size of the listen queue for each TCP-based server endpoint (tcp, ssl, ws, or wss). The default value is 511.

Ice.TCP.RcvSize=num

Sets the TCP receive buffer size in bytes for tcp, ssl, ws, and wss connections. The default value is 131072 (128 KiB) on Windows and 0 on other platforms. A value of 0 or less leaves the operating system's buffer size unchanged.

The OS may impose lower and upper limits on the receive buffer size or otherwise adjust the buffer size. If a limit is requested that is lower than the OS-imposed minimum, the value is silently adjusted to the OS-imposed minimum. If a limit is requested that is larger than the OS-imposed maximum, the value is adjusted to the OS-imposed maximum; in addition, Ice logs a warning showing the requested size and the adjusted size.

Ice.TCP.SndSize=num

Sets the TCP send buffer size in bytes for tcp, ssl, ws, and wss connections. The default value is 131072 (128 KiB) on Windows and 0 on other platforms. A value of 0 or less leaves the operating system's buffer size unchanged.

The OS may impose lower and upper limits on the send buffer size or otherwise adjust the buffer size. If a limit is requested that is lower than the OS-imposed minimum, the value is silently adjusted to the OS-imposed minimum. If a limit is requested that is larger than the OS-imposed maximum, the value is adjusted to the OS-imposed maximum; in addition, Ice logs a warning showing the requested size and the adjusted size.
