As much as I love SQL Server it has dropped in the TPC scores since that MS article was published in 2003. SQL Server 2005 is in the top 10 in all areas except the 10TB TPC-H (ad-hoc/decision support) and only holds the #1 position in the 100GB TPC-H.

It is possible that the hardware used for the tests is the primary factor but I haven't looked into it in a lot of detail. I would like to see comparisons of the top DBMS platforms running on the same hardware.
