what kind of strain does running webalizer have?

I never run stats on my server before and was gonna mess around with webalizer. it seems straight forward enough.

what im wondering is what part of a server does running this affect the most with a high traffic server?

specifically im wondering if you have enough ram and cpu power free so the hard disk isn't swapping does that mean its doing its job as fast as possible?

what warning signs would I be looking for if I want to run these stats for my own use to keep track of data transfer for billing?

thanks!
