[K_meleonu]

Hi there all,
I have a HP Proliant server with 2 CPU's. Each CPU has 2 core's, that means 4 cores.
I want to make a CPU load balancing for it.
My OS is Ubuntu 10.04.2 LTS
( Linux smotocica 2.6.32-33-generic-pae #70-Ubuntu SMP Thu Jul 7 22:51:12 UTC 2011 i686 GNU/Linux
Ubuntu 10.04.2 LTS )
In htop i see thet my CPU cores are used "like hell".
You can see that in the attached image.
Does anyone know's how can i make the to be used equally?

Thank you all in advance for your answers / sugestions.

Best regards
