We’re running a dedicated server with 7 different WordPress networks, with approximately 20-40 sites per network. The websites are primarily informative, involving a low amount of images. Nothing too crazy going on with them.
Our server specs are as follows:
– Intel Core i3-3220 3.30 Ghz
– 2 drives 1000GB each
– 12,000GB bandwidth
mysql is running around 300-400% CPU and is making the server unstable – causing it to crash randomly.
We aren’t currently using any cache plugins, maybe that would help?
Do you have any suggestions on reducing the load of mysql?
