I have a P7 795 (SMT-4) LPAR with 1.5 entitled CPUs and 8 virtual CPUs. I create daily NMON files with 1 minute snapshots.
During my peak busy period there are at most 3 physical CPU units used. Generally, during steady state there are 1.8 physical CPU units used on average.
However, I noticed the RunQueue is continually reporting an averaage value of 4.
Why is my RunQueue always occupied when I have 8 virtual CPUs?
