So for example using the default "event" mpm values (http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/extra/httpd-mp m.conf.in) below in Apache then PHP-FPM would be the same ...
StartServers 3 -> pm.start_servers = 3 MinSpareThreads 75 -> pm.min_spare_servers = 75 MaxSpareThreads 250 -> pm.max_spare_servers = 250 MaxRequestWorkers 400 -> pm.max_requests = 400 I am not seeing any PHP-FPM equiv settings for ... ThreadsPerChild 25 MaxConnectionsPerChild 0 Correct?
