After upgrading RHEVM from 3.0 to 3.1, CPU utilization is very high and postgresql and engine-service processes are consuming a lot of CPU
Issue
- Most CPU time is spent in userspace:
00:00:01 CPU %usr %nice %sys %iowait %steal %irq %soft %guest %idle
00:10:01 all 42.15 0.00 13.18 0.02 0.00 0.00 0.13 0.00 44.52
00:10:01 0 46.16 0.00 14.58 0.04 0.00 0.00 0.18 0.00 39.05
00:10:01 1 44.90 0.00 15.16 0.07 0.00 0.00 0.22 0.00 39.65
00:10:01 2 46.03 0.00 14.93 0.02 0.00 0.00 0.16 0.00 38.86
- And postgresql and engine-service are consuming a lot of CPU:
