[CentOS] CentOS 4 vs 5 for VMware?

[Donald Maner]

I compiled my own kernels for c4 and c5 that dropped the HZ down to 100.  For me, it's a big improvement, especially when it comes to keeping the clock correct in the vm.  And yes, performance is slightly better, because the vms aren't killing the hardware with unnecessary cpu usage trying to process all those ticks.

Thanks for the kernels.  Hopefully they will be eventually added to the centosplus repos.

Very interesting.  Wasn't aware of that.  Thanks for posting.  Have you
noticed tangible differences when running stock vs the kernels
mentioned there?
