Sure. The way that php-fpm works is that there's a php-fpm daemon, and requests for whatever.php are proxypass'ed over to it. So there must be at least as many threads over on the php-fpm side as you have active over on the httpd side, or there will be thrash in creating those threads when the time comes. So basically you need to line up the php-fpm config with your httpd config, or at least have more threads on the fpm side. pm.min_spare_servers (and max_spare and start_servers) are php-fpm configurations, which you'll find somewhere in /etc/php-fpm.d or whatever your particular distro calls it. > > > > On 1/12/16 12:20 PM, "Rich Bowen" <rbo...@rcbowen.com> wrote: > >> >> >> On 01/11/2016 04:51 PM, Rose, John B wrote: >>> After switching to mod_php from php-fpm we are told the site is working >>> 4x faster using mod_php instead of php-fpm. >>> >>> Any explanation? >> >> >> >> >> >> The cynic in me things that this is a case of old dogs being unwilling >> to learn new tricks. >> >> Other things that come to mind is that fpm is grossly misconfigured - >> perhaps they allocated insufficient memory to it?
