Hello all, I a bit curious, what other factors that the availability of CPU-time can cause latency for processes scheduling?
I have a few M5000 running 127111-10 with lots of CPU-cycles to spare, but according to microstate accounting threads sometimes spend ~5-35% of their time waiting to be scheduled. Total idle time reported by vmstat is about 60-80% and mpstat shows that no cpu(hwthread) is utilized to even near the 100%. I've also seen that the run queue sometimes goes up to 2 while we still have lots of cpu-time left. The OS-instance have ~3k5 processes running with ~ 31k6 threads.
