We have had YARPP on our 100,000 visitors per month site for a long time and never really had any problems. When I monitored the server during high traffic times in the past, YARPP didn't seem to slow us down.
About a year ago, we started having major problems on our Hostgator VPS and Hostgator frequently blamed it on YARPP. YARPP has been very useful to us but I disabled it, and the problem continued.
Then Hostgator recommended I upgrade our VPS and I upgraded it 2 levels from our $79 a month level 4 hosting to a $130 per month Level 6 hosting.
I later discovered that I made an error in some custom mods in our theme and corrected them, which seems to have fixed the resource issue.
Lately, things have been much better, with server loads less than 0.5 (ideally, we should be at 2 or lower) but randomly every once in a while for a minute or two, the server load spikes to somewhere between 50 and 100, usually at normally low traffic times.
Hostgator said they think it's just "normal traffic" but it seems unlikely that we would have 200 times our typical heavy load traffic during 1 or 2 minutes of typically slow time from "normal traffic". They sent me a cut and paste response, recommending that I upgrade the VPS again or even get a dedicated server, but we're already spending more than we can really afford at $130 per month and 2 major upgrades didn't seem to overcome these spikes.
So my 2 questions:
1. Does anyone else have random huge server load spikes with Hostgator VPS?
2. Do any of you using YARPP find that it sucks a ridiculous amount of server resource? To me, it doesn't seem so (when I monitor real time resource usage) but Hostgator insists that it does.
We like YARPP enough that we are considering changing hosts to see if the problem really is YARPP or Hostgator.
I keep feeling like something is wrong at Hostgator and I am frequently sent to back to the Level 1 tech with the "cut and paste" answer, which is really aggravating, since the Level 1's never answer my question.
If you can shed some light on this and share whether or not you've had any of these experiences, I would greatly appreciate it.
We typically have 100,000 visitors per month on our Wordpress site on a Level 6 VPS, which includes:
CPU: Dual 3.4 GHZ
2304 MB RAM
1800 GB Bandwidth
We're also using caching, gzip, and a variety of other load reducing tools.
Thank you in advance for any suggestions!
