|Summary||0002320: Follow-up to Bug#2189 - Getting optimal performance in a virtualized environment|
"In 2.4 kernels the system timer was normally clocked at 100 Hz, while in 2.6 the default system timer is set to 1000 Hz (some other distros are not following these "rules", and USER_HZ is still 100). 1000 Hz is definately a good thing for desktop computers requiring fast interactive responses, but there are environments where this causes bad side effects.
It would be a great benefit if a 100Hz unicpu kernel was made available in one of the CentOS repositories."
We will continue the discussion in this bug report.

The last point of discussion in the original report was naming of the 100Hz kernel. It looks like the name "kernel-vm" is going to be used. Kernels running at 100Hz have been rebuilt for c4 and c5 using this new name. Thanks to danieldk for creating the spec file for c5. Both c4 and c5 kernels are temporarily available from:
c5 is at 2.6.18-8.1.8 and the latest for c4 is 2.6.9-55.0.6. I have made these available for anyone who wishes to test before the official version is built by CentOS.
