My b2evolution Version: 2.x
Months ago I switched my web hosting to InMotion, which is recommended for b2evolution users.
Since then, they have advised me my blog at comiclist.com is using too many resources, and I need to switch from a $50 a month VPS to a $200 a month dedicated server.
Installing an APC cache has not helped with the matter.
One detail they recently gave me was "So far today there have been 1800 slow queries, and your vps container averages 20 mysql queries per second."
Back in September they said "Currently your VPS is using around 10 times as much CPU as is appropriate for the platform and has been doing so for a several days. Each load of your index page uses 75%-90% of the server's available CPU. Usage of the side menus also drives up CPU utilization. We suggest that you optimize your theme to cache as much information as possible and make whatever adjustments possible to decrease CPU utilization. If your site is already optimized as much as possible, you will need to consider upgrading to a dedicated server platform." I eliminated a RSS plugin that seemed to be a resource hog, but to no avail.
What does this mean? How can I fix this? Or am I doomed to paying for a dedicated server? What am I doing wrong?
