It's going to take a while to fill it all in because I'm doing it in free time of my job, but I'm putting up results as I get runs done. You can see the results at http://www.simplified.org/trac/wiki/InterruptCoalescenceTesting as I complete them.

Over the weekend the /var/log partition on the test run server filled up. As a consequence both the routing engine and Asterisk slowed way down. However, neither died, and upon clearing up space, both resumed normal operations. We're now past the 12 million call mark. After 20 million calls I'll switch to the new data set that should allow us to sustain 300-350 calls per second and I'll report again after the 100 million call test job completes.

I've started running some stress tests of both SIP signaling and RTP handling in Asterisk 1.4 and Trunk. In our telecomm routing project we needed a SIP front end to our route selection server and the choice became Asterisk. However, we need to be able to push at least 400-500 calls/second through Asterisk to any given Griffin server. To do this is going to require some work on the Asterisk side of things (as well as a herculean effort on our Griffin development team).
