This spring there has been extensive benchmarking done with the Itron team on Itron Enterprise Edition Meter Data Management and Microsoft SQL Server 2008 R2 Enterprise, which I have been following. A few weeks ago there was a webcast with Itron's Robert Sonderegger and our own Lonnye Bower, describing the preliminary results. Preliminary public results tend to be conservative to avoid egg-on-the-face syndrome. Today I received the final report (June 6th, 2011) while eating a very spicy Mexican meal -- I am not sure which was hotter. You can read the report here.
A few new items that I spotted were:
You should compare these results to those obtained on SQL Server 2005 reported here -- SQL Server 2008 R2 Enterprise with IEE MDM v7.0 SP3 pushed the benchmark more than 3x higher! Congratulations to the engineers at Itron and Microsoft for a job well done!
