This put a smile on my face:
Miercom did some load testing with the Lync, and had the following to say about it: "Microsoft Lync Server 2010 passed an aggressive SIP Load Torture Test without dropping any calls or reporting errors in the 4,000,000 call attrition test. This sustained operation without error is the best we have seen to date for any Unified Communications / IP PBX product we have tested".
Hmm.. according to the document, the entire setup was run off a Hyper-V server with single i7 quad core proc and 16GB of RAM? Or am I missing something... DC, Exchange, Sharepoint and all?? Wow. I wonder how they broke up the roles for Lync or was it mostly collocated on the Mediation server..
