Hi ,

If you have doubt, whether you are using all the cores of your processsors,

Run the top Command and once your run , type the number 1

On the top of the screen you should see the CPU usage for each of the cores
that are being used in your system.

I Am using smp kernel for a twin quad core Xeon cpus, and shows 8 cpus from
0-7, the system has 6 gigabytes of ram, and they are all reported there with
the top command.

Stephanie, could we discuss this a little more?  I have an HP DL380 G3,
which is dual 2.8Ghz Xeon processors.  I have been running the PAE kernels,
thinking that was required to access my 6GB of RAM.  Are you saying that I
might be wise to try an SMP kernel to get better performance?
