The defaults for php-fpm. So none match and are set lower in PHP-FPM.
Except of start servers
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.max_children = 50
What would this match to in Apache?
? -> pm.max_requests = 0
These do not seem to have a matching setting in php-fpm from what I have
seen
ServerLimit 16
ThreadsPerChild 16
MaxConnectionsPerChild 0
Not sure how prevalent Apache/Event/PHP-FPM is, but a table correlating
the Apache config settings and PHP-FPM config settings would be useful. At
least for initial setup.
So, is this accurate ...
StartServers ? -> pm.start_servers = ?
MinSpareThreads ? -> pm.min_spare_servers = ?
MaxSpareThreads ? -> pm.max_spare_servers = ?
MaxRequestWorkers ? -> pm.max_children = ?
No Apache equivalent -> pm.max_requests = ?
ServerLimit ? -> no PHP-FPM equivalent
ThreadsPerChild ? -> no PHP-FPM equivalent
MaxConnectionsPerChild ? -> no PHP-FPM equivalent
