I have a VPS running Centos and a Cpanel installation. 2 GB RAM.
It currently runs Apache 1.3.42. I could also use 2.0.64 or 2.2.22, should I upgrade?
PHP (5.3) runs as SuPHP.
I'm wondering if I should stick with the current setup? Or should I implement FastCGI and use a PHP opcode cache (APC, XCache, etc)?
I'd like to use an opcode cache if possible to speed up my page generation time, however I've read that running FastCGI on a VPS can increase the server load.
What are the security implications of SuPHP versus FastCGI?
