Subject Re: activemq 5.3 slower than 4.1.2?
Date Tue, 09 Feb 2010 02:04:07 GMT

Found a thread in the forum on similar issue that links to

We tried, and do not observe the blocking issue so far. However, the
performance dropped, with the average response time now at about 600ms. We
set the usageManager limit to 128MB and tried 512MB as well. Are there some
other configs that we can tune further?
