[tarakdesai]

Hi,

We are running web/DB server combo with 8 Cores/ 16GB RAM / SSD drives cpanel server having apache 2.2 and mysql 5.1 server. Site is 100% dynamic in php/mysql with data been updated every few minutes.

If we want to migrate to litespeed - how many cpu license we need to buy ? 8 cpu license as web server have 8 core on Xeon QuadCore E3-1230 ?

And will litespeed be a major speed boost for such dynamic php/mysql based application ?

Please Advise.

Thanks
