FastCGI for PHP makes all your PHP applications run through mod_fastcgi instead of mod_phpsusexec. FastCGI applications are fast because they’re persistent. There is no per-request startup and initialization overhead. This makes possible the development of applications which would otherwise be impractical within the CGI paradigm (e.g. a huge PHP script, or an application which requires a connection to one or more databases).

Benefits:

– PHP scripts will run faster. The PHP interpreter is loaded into memory rather than calling from storage for every hit, greatly improving performance of your scripted site.

– You will use less Server Resources. Since the server does not have load the PHP interpreter for each hit, you will be able to accommodate a higher traffic site without exceeding your CPU quota.

– NO modifications to your existing code are required. Everything you currently run will work with FastCGI for PHP.
