PHP 5.3 FastCGI or CGI?

Hi. I’ve been browsing different threads and it seems like the general idea is that if I use PHP 5.3 CGI instead of FastCGI I will have lower RAM usage and a faster server. Is this true? Should I switch over all of my domains on the VPS to just PHP 5.3 CGI?


What I did was use a stop watch and 10 repeated loads of my homepage. Try with with fast CGI and without. On my sites fastCGI was slower.


Well that is one way of doing it. :smiley:

Is there any reasoning why CGI would be faster than FastCGI?

No, the opposite should be true.

CGI has to start a new process for each and every request, where as FCGI is persistent. To say FCGI is slower is a bit like saying memory caching will make your site slower.

If you’re using Wordpress, WP-Super-Cache + PHP CGI works best, giving you very low RAM usage. That’s because you don’t need PHP to serve cached files, saving you RAM.
