You could build something around the following command (read the man-page of "ps" for an explanation of the options used:

Code:
ps -Alo pcpu,vsz,pid,args | sort -rn

Basically this lists CPU consumption (pcpu) and virtual memory consumption (vsz) for each process and sorts for CPU consumption.

Again: read the man page of ps and that probably becomes clearer. You might also want to read Demystifying IOWAIT and AIX Process Priority and Control.

I hope this helps.
