I mentioned a while back that my WordPress blog had a problem with excess CPU usage. I’ve never been able to get the CPU usage under control. I tried WP SuperCache. I tried disabling plug-ins. Nothing really worked.
I eventually downloaded WP-DBManager and used its repair and optimize functions. That made the biggest difference by far. I’ve gotten my CPU usage down from 20%+ to 3-5%, but it’s still not good enough. I suspect some database corruption.
All the same, I’m moving the site to HostingMatters along with some other domains and projects. If the site goes down this week, it’s because the old server went down before the new server came up. I’m trying to avoid that if at all possible, but it could happen.
