I noticed the default setting for "pm" in php-fpm.conf is "ondemand". According to this post, "ondemand" is best for shared hosting environments which will have a high number of low-load pools. I am running a single high-traffic site on my server in one pool (I think), and that post indicates "static" would be the best for me, presumably because this means the processes always exist and don't have to be created "on demand". Is this a setting I should modify or should I just leave it as is? Thanks!
