I am experiencing high CPU steal percentage in a Amazon EC2 large instance. I know it means that my virtual CPU is waiting on the real CPU of the machine for time. My question is that what can I do to reduce this percentage and get maximum out of the CPU?
Steal percentage is consistently at 20%. System load crosses 10 when this happens. I have checked memory and network and I am sure that they are not the bottleneck. Is that normal for such environment?
Also are there any system level optimization techniques for reducing steal percentage form the virtual instance?
avg-cpu: %user %nice %system %iowait %steal %idle 52.38 0.00 8.23 0.00 21.21 18.18
