Sun Java System Web Server 7.0 Update 3 Performance Tuning, Sizing, and Scaling Guide

Tuning CGI Stub Processes (UNIX/Linux)

In Web Server, the CGI engine creates CGI stub processes as needed. On systems that serve a large load and rely heavily on CGI-generated content, it is possible for the CGI stub processes to consume all system resources. If this happens on your server, the CGI stub processes can be tuned to restrict how many new CGI stub processes can be spawned, their timeout value, and the minimum number of CGI stub process that run at any given moment.

Note –

If you have an init-cgi function in the magnus.conf file running in multi-process mode, you must add LateInit = yes to the init-cgi line.

Tune the following settings to control CGI stubs. These settings are on the configuration's Performance Tab ⇒ CGI sub tab.
