Subject Re: Poort ActiveMQ Persistence Performance
Date Sun, 20 Apr 2008 18:53:25 GMT


Hi, Rob

I've been doing some testing with ActiveMQ 5.1, making it receive messages
as fast as possible. What I noticed was a steady slow down as the messages
kept coming to AMQ. I have to mention here that I intentionally didn't
consume messages from the queue (so it kept growing) to see the storage
capacity of AMQ.

Below are partial results of sending messages over 100MB network using
OpenWire to AMQ 5.1 running on FreeBSD.

The trend of performance decrease suggests a possible bottleneck in the
persistence module (which was Kaha by default). Obviously, I cannot assert
this for sure. 

Even though Kaha is supposed to be the fastest storage mechanism supplied
with AMQ, are there any configuration options to fine-tune it for heavy
loads? 

This is a part of the more broad issue "how to make AMQ accept more messages
per unit of time, thus reduce number of nodes in a cluster".
