[EN] PHP-FPM vs. mod_php from Apache

For me, the following picture says everything:

CPU ussage


The change was done around 16 o'clock. You can see that the CPU usage dropped with ~100% (4 cores => 400% max usage). Each PHP-FPM process is using ~25-35 MB of RAM memory, comparing with 2 apache processes with 16 threads each which were using ~200 MB of RAM memory each.

I will test it for some time and i will return with detailed conclusions.
