Server load excessively high (three figures!!) after migration

[CTXMedia]

I can restart my server and run CycleChat XF as a closed board and it runs just fine. No problems.

As soon as I open it and my members begin using it the server load starts rising and rising and it takes longer and longer for pages/posts/actions to complete, to the point it becomes useless.

Any ideas about what I might have missed, or misconfigured?

Thanks,
Shaun

I get the same on my IPB install (0.5 load and below) with consistently 100-200 guests online (never mind the members), so good job
