If you want FPM to do it you need to use the dynamic spawning then ( edit
pm = dynamic
and change the following settings to your needs:
Otherways if you use 'static' process manager just increase pm.max_children
The error_log should even contain some information if there is a need to
tune theese params.
Jul 12 20:14:20.869487 [WARNING] [pool www] seems busy (you may need to
increase start_servers, or min/max_spare_servers), spawning 32 children,
there are 0 idle, and 66 total children

setting (70), consider raising it

request_terminate_timeout = 60s
request_slowlog_timeout = 20s
slowlog = /path/slow.log
slow.log then will have backtrace of which script and what part of it takes
too long (in this case 20 seconds).

documentation is for the old style XML configuration the variables are still
