There are so many other variables. 
Hopefully this helps a little bit. Oh, also check your status reports and logs to make sure you have no errors.

Good luck.

Dear All Drupal Experts
I have a site hosted www.netcloudjobs.com.
It was working OK, page loading was bit slow.
I slower connections sometime it was not loading.

My environment is
CentOS 6.3 final
Apache 2.2.15
MySQL 5.5

I installed APC by
yum install php-pecl-apc

Then I downloaded APC from drupal site and enabled.

I added settings entry in my settings.php

After that, I see I am unable to access my site.
Most of the time it says connection reset.

Can somebody point me whats the wrong I am doing here.
