I know this question depends on a lot of things, but I got a site with about 500 visitors and around 800 pageviews, nothing crazy. I do have W3 Total Cache installed and using Amazon S3 as CDN. But today my host told me my site used around 65-70 PHP processes, so they disabled my site for a while.
I have been looking at the CPU usage (shared hosting) all day, it does spike sometimes (700-1000 %) but it also happens when there's no visitors or my site.
So is 65-70 PHP processes way to many for a site my size or is it my host that got too many accounts on the server I'm on ?
