I've been having an increasing lack of performance in my server (slowness, stalling on page loads, largely backend issues where I spend most of my time) over the past month or two on what is primarily a standard blog. The site gets 20k hits a day though I even have these issues on weekends when traffic is lower as well.
- Knownhost VS3 (VPS) / Apache / RAM: 1216 MB
- Optimizations: WP Super Cache & Cloudflare (CDN)
- Memory usage typically at 15-20% / Hard Drive: 50% of 60GB
I tried uninstalling Super Cache & installing W3TC. That brought some additional issues including finding out the hard way that we couldn't enable object caching.
Server issues have been ongoing for the past couple years with a few different companies. It's not new/recent, just getting worse.
My main question is whether the plugins I have enabled could be creating these problems as my host suggests & if so, how do I reduce the number of connections? PConnect is not a possibility where I need caching.
See the host's message below...
