Environment: Oracle Virtual Machine, 8 vCPU, 32GB.
I am seeing context switching averaging around 10000, but at times hitting 80000. It does not correspond to CPU SY% more than 2-3%. The CPU% still shows ~40% idle or so while load average at 60 or so (too high). CPU iowait between 40-60% at times.
Based on researching this, it seems
- All of this has to do with IO waits.
- The high context switching is not expensive since cpu sys is still very low. Thus I should not concern myself with it.
No idea why the load average is this high and the same time CPU shows ~40% idle.
Thanks for your input.
