Hi,
I suspect a CPU bottleneck in one of our PostgreSQL servers but not sure how to confirm the suspect.
It's a DELL Box running CentOS 5.4 with 64GB RAM and 16 XEON E7430 2.13 GHz processors. vmstat r column "run queue" usually indicates values higher than 2 and less than 5 but "Load Average" values from top, sar -q and other commands show always values less than 1.
Should not these values be higher than 16 on a box with 16 processors to confirm a CPU constraint?
Thank you in advance!
