Subject Performance
Date Mon, 10 Jan 2011 00:09:49 GMT
I'm running performance tests and noticing that under load I am getting increasingly large
amounts of time spent in the SEDA queues.

For example below are some lines from my log when the app is under load (20 concurrent threads).
The first is from one Route (Get360List) that then call the calls the 3 routes via multicast
in parallel (GetPolicyList, GetFeeList, GetClaimList).

There is a ~600ms delay between the multicast being called and the Consumers on those SEDA
queues picking up the messages. I have 30 concurrent consumers set for each SEDA endpoint,
so I would have thought that there would be no shortage of consumers to pull messages from
these queues.

Are there any other settings that I should be looking at to reduce this delay?
