We have a wordpress 3 installation on a fresh new dedicated server. Our website was working fine for about 1 year before on a very smaller VPS. After changing our hosting platform, we moved the website to our brand new windows server, but there were lots of problem with windows (long file names and ...). Finally, we bought a new linux dedicated machine (Quad core cpu with 4GiB of ram with cPanel and WHM (CentOS 6)).
On the new server, the website is DEADLY SLOW, page load is about 1 minute!
I've tried almost anything, from wordpress cache plugins (W3 Total Cache) to increase memory limit (php.ini and wp-config.php) and anything else I can think of...but nothing changed.
Could anyone help me please?
NOTE: the administration panel of wordpress is working fine. I am really mixed up :-/
