Radhakrishnavangara,

If your app is pure PHP (and perhaps some Javascript/AJAX) and you have no intention of migrating to another platform, your best bet is sticking with Apache httpd and troubleshoot your performance issue.  Otherwise you're just making things more complicated.  As Alan pointed out, there downside to running PHP as CGI which you may want to consider is worth it to migrate to another platform server which has no main use for you?  If you do intend to migrate to another platform, then just follow as Johnny pointed out.

As for performance, rule which i go by is "run lean" meaning take out any httpd mods and any php extensions you have no use for (you will need to refer to Apache httpd's and PHP manual for this).  By removing unnecessary mods and extensions, you reduce the memory consumption.  Then start looking at your server/system for unnecessary processes/services (you'll have to refer to your OS documentation for this).  If it's still running slow, then you'll have to the dirty work of debugging and fine tuning your app (if you didn't build it, you may refer to developers/provider whom  build it for help) since the app you use may free the resources it consumes.  Thus, as time goes on, your server will be running slow.  This is a problem with all apps regardless of what server/platform the app running is on.  Some server/platform has some method of "garbage collection" but you'll need to read the server's/platform's documentation to know what you have to work with.

Regards,
Tommy
