Subject RE: Activemq vs. Rabbitmq, performance Peaks
Date Mon, 27 Jun 2011 15:23:54 GMT
I noticed a similar trend of spikes in latency when I was testing AMQ 5.3.0/5.3.2, and I could
link them to log entries for opening new kahadb journal files.  In our case it was tied to
synchronous disk IO performance, but it was still faster than what we needed, so we didn't
worry about tuning kahadb or our disk.

Havea you correlated those peaks with specific times in the activemq log?

Probably a long shot, but maybe its the garbage collector in the JVM?
If so, you can adjust the schedule for it.
