IBSIZE (JANUS DEFINE parameter)

<section begin="desc" />xxx<section end="desc" />

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

This parameter specifies the size of the TCP/IP input buffer. The default is 4096, the minimum is 512, and the maximum is 65534 (prior to version 5.2 the maximum was 32767). 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.
