WebPageTest

Pat, thanks for pointing me in the right direction (as always).

The site is a vBulletin-based forum , so yes, it is PHP. The server runs Apache. The old server used LiteSpeed plugin, which I'm not certain is needed, but I will test the site with and w/out it on the new server, too.

The VPS has just one site on it, so I can chose any configuration that suits the site best, w/out worrying about negatively affecting another site.

I'm now comparing the Apache options enabled in the old vs new VPS. The following is a brief list of the options that are enabled on one, but not on the other VPS:

OLD VPS:
EAccelerator for PHP
IonCube Loader for PHP
Mod Security
Zend Optimizer/Guard Loader for PHP
Proxy
UniqueId
Version


NEW VPS:
Mod SuPHP
CGI

Should I disable the Mod SuPHP and CGI on the new server, and enable some (or all) of the options of the OLD server listed above?
