IBSIZE xxx — Size of input buffer

IBSIZE is a parameter on JANUS DEFINE, which defines and sets characteristics of a Janus port.

This parameter specifies the size of the TCP/IP input buffer. The default is 4096, the minimum is 512, and the maximum is 65534. There is one input buffer used for each connection.

A larger input buffer size provides better CPU performance in both Model 204 and the TCP/IP address space at the expense of more virtual (and real) storage. Generally, the size of the input buffer has an impact only on a port being used for Janus Open Client or Janus Sockets connections or on a Janus Web Server port used for file uploads.

Valid for all port types.
