&gt;So we may not be making money these days, but with this benchmark we are doing it faster. <div>&nbsp;</div> Who told that IBM faster ? There are no competitors on 16 cores ... why don't IBM use DB2 UDB in this test ? Problems with concurrency without snapshot isolation level ? Why IBM don't publish Power6 results ?

Thanks for your comment. Yes, it would be nice to see even more results at 16 cores, as well as results using other databases and other technology platforms.

Right now, TPC-E is not really useful as there are only results from SQL Server. What's going on with Oracle and DB2?

TPC-E is very useful if you check t-sql code from benchmarks. In TPC-E Microsoft avoid temporary tables, use 64 equal indexes on 64-core system, IL read committed was replaced by IL snapshot in first published result and many others interesting things ...

Remember that TPC-E has a complex database layout and transactions, many more tables, columns, keys, and tables with foreign keys, and referential integrity, as well as customer partitioning and database isolation requirements. <div>&nbsp;</div>
