Performace Issue (CPU time)

Hello,
We have a V2r5, 4 node system and here is the issue.
Assume we have 3 groups (Group A, Group B and Group c) in our company.
if Group A complains that the system is running slow,
what is the best way to find the CPU used by each group?
How can we find if one group is using most of the resources and other group is waiting for the resources?

Thanks
