Apache using alot of the CPU

I've been running a site for quite a while now and apache have never eaten alot of the CPU it's usally around 1-5 % .. but now it's sometimes using about 70-80% of the cpu's.

I've been adding a script that restarts apache every 5 min in order to load new virtualhosts. Do you think this is why it is using much more power than before?

Any other way I could do that?

Maybe some other tricks or tips?

How can I get an average cpu usage?

Thanks.
