wow, my hosting service shut me down for using too much load on the server.
i'm trying to figure out what to do.
We have a well established site with thousands of posts. It's both of a database issue and a plugin issue. The problem is
1)database connections; my site creates multiple server connections which don't seem to be closed.
2)we have lots of plugins. too many, and they are not well tested.
3)we are 2 or 3 months behind on upgrading.
4)we tried to install wp super cache, but this caused the meltdown. (even after we deactivated it)I don't think super cache caused the meltdown, but it was certainly the trigger.
The hosting service has removed the website because of our mysql problems, but I can restart it gradually.
I'll upgrade, install wp-super cache (or alternatively wp-cache). then the theme, then one plugin at a time (all 20 of them!). but i just don't know how to measure website/plugin performance. How do you do that? How can I tell which plugins are dragging me down?
