Hello! I have my own dedicated server and i've contract the litespeed to use on my customer websites... this is a good tools to speed up your wordpress and magento websites.

I want to know if is possible to active this to work with my forum too, because today the google will give preferer if your site is too fast.

It is not true that Google gives preference to the fastest website. I had to add a line of code in the Robots.txt to limit the speed, when you have 95% of the robots hogging your bandwidth..
