RE: Activemq vs. Rabbitmq, performance Peaks

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

RE: Feasibility of Shared File System Master Slave using NFSv4

2011-05-19 Thread Idzerda, Edan
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
