Dear Gentlemen,
Thank you very much for your help so far. I was certainly looking for
the "S" option. When you are tired these things are easy to miss.
Here is an output of the system with the md driver removed and
everything is on the hard drive for now. The system usage is still really high.
Does anyone have any suggestions based on the output below?
Thanks
Paul

My system is being killed by a system cpu always between 50-70% on
Freebsd 6.2 with SMP enabled. Does anyone know of a quick tool to be
able to tell me what is making up that 50-70% for the System Cup Usage.
Uh you had the right idea but forgot to paste the relevant bits ;-)
top *is* the tool for working out what processes are using your CPU.
Although your high load average suggests that your system is just
heavily loaded and it is expected that it will be using 100% CPU.
Maybe Paul havn't found "S" in top?
Enter "S" when runing top (to show system processes) and you might
find out more about whats going on.
