OBSIZE (JANUS DEFINE parameter)

<section begin="desc" />OBSIZE xxx &mdash; output buffer size.<section end="desc" />

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

This parameter specifies the size of the TCP/IP output buffer. The default is 8192, the minimum is 512, and the maximum is 65534 (prior to version 5.2 the maxiumum was 32767). There is one output buffer used for each connection.

A larger output 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. See IBSIZE, BSIZE and RBSIZE.

Valid for all port types.
