Ironically, many platform Vendors choose CENTOS which is Redhat/RPM based, "because" they're supposed to use stable / tried and tested versions of Linux. Unfortunately, what you tend to gain in "tried and tested", you tend to lose in "bug fixes", "features" and "performance". (if you download appliance CD's for things like trixbox etc, they're all CENTOS)

For anyone out there tempted to try CENTOS because the "E" in the name stands for "Enterprise", don't be fooled.
It's "nasty".

For anyone out there wondering why the "latest" Centos image running under KVM is eating between 15-20% of the CPU when idle, while their Ubuntu image is eating less than 1%, please refer to "It's 'nasty'". Then edit your grub.conf and add

Code: [Select]
elevator=noop divider=10

To the "kernel" line, then reboot.
That should knock it back to 1-2%.

Wow, 15-20% idle for a SERVER OS? That is nasty...
If you try to look through Windows, you can see what the person is doing.

Absolutely, CENTOS is nasty.

To really amuse you, this is from the very latest version of Elastix (CENTOS hosted appliance);
