We have two Windows Servers 2003 Ent setup as a cluster. Both have identical hardware except RAM, node 1 has 4 GB and node 2 has 2 GB. On node 1 the CPU utilization for all 4 cores is always same. On node 2 only one core (core # 3) shows CPU utilization high enough and the other three cores have very low CPU utilization. Please see the attached JPG. We noticed it becasue of the slow performance we have been experiencing lately. Does any one know why the CPU utilization is not same for all cores on node 2 and is there a fix for it?
