I've heard about PHP-FPM about a month ago from DirectAdmin webboard. Then, a few weeks ago, I had a couple websites that I need to make it run faster. After tried to do many things with it like ... to use mod_fcgid / XCache / Memcached, I feel like there was something in XCache since "Page execution time" is quite high. Then, I remember that I've read from many websites that XCache doesn't really work with mod_fcgid. From the technical point, all of them explained it clearly to understand.
