Subject CPU bound workload
Date Wed, 07 Dec 2011 22:08:09 GMT
I've got a batch process running every so often that issues a bunch of
counter increments. I have noticed that when this process runs without
being throttled it will raise the CPU to 80-90% utilization on the nodes
handling the requests. This in turns timeouts and general lag on queries
running on the cluster.
Is there anything that can be done to increase the throughput, I've been
looking on the wiki and the mailing list and didn't find any optimization
suggestions (apart from spreading the load on more nodes).

Cluster is 5 node, BOP, RF=3, AMD opteron 4174 CPU (6 x 2.3 Ghz cores),
Gigabit ethernet, RAID-0 SATA2 disks
