Subject Re: Slow throughput after several hundred messages
Date Tue, 14 Dec 2010 10:27:04 GMT

I have left the test application running over night, it is still consuming
and producing messages but is blocking very often now (every 15-20 seconds
for around 10 seconds each time). 

I used visualVM to analyse the garbage collection, which seems to be running
around once every two minutes or so and taking around a second to complete.
The JVM heap is around 60% of the max heap size. I have attached heap dumps
from previous runs in earlier threads. I have taken a heap dump of the
broker, still under load after 17hrs uptime, but the compressed file is too
large to upload onto this forum. I checked the heapdump for LRUCache, but
this has 9 live instances, unlike in the issue described in AMQ-3028.

I will now bounce the server and turn on garbage collection logs as well.
