I have been using Apache on my local LAN. The problem is that i recently installed APC (along with PHP5-dev and apache2-dev). Now the response time of Apache has reduced. It roughly takes 2 seconds to for a php page to load, where as earlier it took around 500ms. Although in firebug is shows the old response times.

Why is this so? How should i fix it?

Thank you very much.

**Update** Which server should I install incase I reinstall it? I want really blazing fast LAN response times from my server. I am planning ubuntu desktop 9.04. Or should I use ubuntu 8.04 server? or ubuntu 9.04 server?
