Subject activemq fast on laptop but slow on desktop pc
Date Sat, 27 Jul 2013 10:20:09 GMT
I am running a stress test of activemq. I am publishing a big string 10000
times on a queue. It all works very fast on my laptop but on my desktop
(which has faster disks) it is very slow. Also on the desktop I can hear the
disk struggling to cope, like it tries to do a lot of seeks.

Here is how I start up activemq:

./activemq console
xbean:/home/ariskk/idea-workspace/backend/config/jms/activemq-stress.xml
INFO: Using default configuration
(you can configure options in one of these file: /etc/default/activemq
/home/ariskk/.activemqrc)
