php-fpm is documented in the PHP docs at http://php.net/manual/en/install.fpm.php I'm far from an expert on it, but the rule would be that if you're proxing from A to B, then B needs to be able to handle as much traffic as A is forwarding to it. So I'd expect that what you want is at least as many servers/workers/threads on the php-fpm end as you are likely to proxy from the httpd end. --Rich > On 1/12/16 2:03 PM, "Rich Bowen" <rbo...@rcbowen.com> wrote: > >> >> >> On 01/12/2016 01:58 PM, Rose, John B wrote: >>> Can you elaborate on this a bit? >>> >>> "..the server pool is smaller than Apache's server pool, causing >>> too much thrashing.
