isp-control with mod_php5

Quote:PHP under fcgid is actually not too much slower than php as a module (within a few percent last I read), and you have a lot more security keeping it separated.

In fact, static file serving is even faster and less resource-consuming because you can use the threaded apache workers with fastcgi, whereas you can not with mod_php (php is not thread-safe)

Quote:You also have the benefit of lower memory use as PHP is only used when necessary. If you use PHP as a module, it's included in the memory usage even if all that is being served is a static html file or image.

This is not necessarily true. With the default ispcp setup, each php-enabled website has at least 2 php-cgi backends for fastcgi, even when they're never accessed. Therefore, the number of php-cgi processes grows linearly with respect to the number of domains on your server, even when they're almost never used. As a result, the system probably consumes much more memory than if you go the mod_php way. In this setup, all apache workers (processes) can serve requests for any domain, so the total number of processes that you'll need is probably much lower than 2*number of domains...
