Please Help - CPU usage too High with upgraded server !!
Originally had the following Spec server:-
AMD 2400+
728Mb RAM
2 X 40GB HDs
running RH9.0 CPanel/WHM etc
had a hacking incident and decided that whilst doing a rebuild i would at the same time upgrade the server as i thought i only had a few months growth left in it.
I upgraded to:-
Intel Celeron 2.53Ghz
2 GB RAM
2 X 180GB SATA HDs
running CentOS 3.3
WHM 10.0.0 cPanel 10.0.0-C6
WHM X v3.1.0
Anyways the long and short of it is the CPU Usage is always very high and server response super slow. Memory usage is also excessive with
here is a sample TOP with command line showing and sorted by memory usage:-

now according to http://www.xbitlabs.com/articles/cpu...sempron_4.html
my new Server should be quite a bit faster than the old, so how come its running like a dog ???
the server runs around 4-5 fairly busy heavily modded phpnuke sites with prob 2000 uniques overall on the server every day.
Any help gratefully appreciated.
