Fcgid php

This option is only available for DreamHost PS. When this option is checked all PHP files will be automatically run though FastCGI via mod_fcgid. This improves performance by leaving the PHP interpreter in memory for awhile after the first request. Subsequent requests will be faster. With this enabled you can also enable XCache, which further improves performance by caching compiled PHP code in memory so it doesn't have to be compiled again on later requests.

This option requires that FastCGI support also be enabled for your domain and cannot be enabled unless FastCGI support is also enabled.
