Can I run PHP with FastCGI on Shared Hosting?

At the moment we do not support FastCGI on shared hosting although it is an option you can choose in Plesk. This is because the Apache configuration we use to allow Shared Hosting clients to edit php.ini settings through their .htaccess file. With our Apache configuration, the speed gains a site would receive from running FastCGI are negligible in comparison with the ability to edit ini settings for your site.
