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
Have you tried prefetch=0 ? I was doing some similar testing a while ago and
as I recall, prefetch=0 was the setting that behaved best for my round-robin
consumer setup.

I think that's kinda funny, really. ActiveMQ's website has a warning about
potential problems with locking under NFSv3,
http://activemq.apache.org/shared-file-system-master-slave.html and IBM MQ's
similar "multi-instance" mode *requires* NFSv4 for "proper lock handling."
I only briefly teste
