PHP-FPM config

[oparoz]

@jospoortvliet has dug out this from here:

request_slowlog_timeout = 5s
pm = dynamic
pm.max_children = 9
pm.start_servers = 3
pm.min_spare_servers = 2
pm.max_spare_servers = 4
pm.max_requests = 200
listen.backlog = -1
request_terminate_timeout = 120s
rlimit_files = 131072
rlimit_core = unlimited

I'm currently using

pm = ondemand
pm.max_children = 9
pm.process_idle_timeout = 60
pm.max_requests = 200

I think playing with the start_servers could be useful, but we have to be careful with memory usage.

We have to check every setting and make sure they're not the default already.

The web is littered with only configurations, using obsolete switches and options.

Why do we want PHP-FPM? Is it faster? My experience is the opposite.

[jospoortvliet]

@enoch85 yeah, I had bad experiences too, but Tha Intarnetz says that, if configured well, it should be faster and save memory.

[oparoz]

It is faster if you configure it properly and make lots of servers available per example, but it definitely uses less RAM when combine with mpm_event.

I'm going to go with pm=dynamic (on demand is better for shared web hosting), but it's going to be user tunable.
