The independent testing company, Miercom, recently completed performance testing of Microsoft Lync Server 2010.
The tests validated Lync’s overall performance, resiliency, and security. You can check out the report at: http://www.miercom.com/microsoft
One test that I found interesting was the load test. Miercom generated a load of 13,147 calls per hour for 3 days. Lync didn’t drop a single call, so they decided to let it run another 10 days… Lync conducted over 4 million calls with 100% success. This is the highest performing UC platform / IP PBX that has ever been tested by Miercom.
Oh, did I mention that the entire UC deployment tested was running on a single Hyper-V host?
