How to switch from CGI to FastCGI
By default, HostKnox accounts are configured to work with CGI. FastCGI, however, is also available and customers can switch to it any time they want.
FastCGI is a variant of CGI that speeds up and improves the performance of applications written in different programming languages (e.g. PHP, Perl, Python, etc.).
If your site is getting busier, you can try it and see if there are any improvements. You can switch to FastCGI from the Pixie control panel. After you log in, open the PHP Settings section, then click on the link Main Site. On the next page mark the button for FastCGI and click on Change.
It's unlikely, but if there are any problems after the change, you can always switch back to CGI.
