Thanks for your answer! It's so bad. We're building a cluster system over different data centers with glusterfs. The main problem is the latency because of the distance. We solved this issue by using php cache modules, like apc. But to use this with an apache server, php-fpm is required (we don't wan't to use mod_php)... We will continue to watching the development! Best regards
Have you tried fastcgi (not cgi)? Fastcgi is also a daemon process similar to php-fpm that is reused for incoming php requests and can use php binary caches as well.
Your're right. Our tests has shown, that the performance difference is hugh... The concept to spawn fastcgi child processes is slow and needs a lot of memory in contrast to php-fpm...
Thats good to know. Iwasnt aware that there is such a huge difference performance wise. I will see if we can add php-fpm for apache then too.
