Interesting find:
The Truth About the TPC
...
For example, one reader asked, "Why does the TPC organization
only test commercially licensed operating systems and databases?
My presumptions would lead me to think that a non-profit based
organization would be benchmarking anything they could get their
hands on. An example being, why don't they test postreqsql or
mysql on a Linux platform?"
...
However, the TPC doesn't have the power to run benchmark tests
on a database platform without the approval of the database
vendor. In fact, with the exception of IBM, most major database
vendors include in their license agreements a clause that forbids
the publication of benchmark information without explicit
permission. Here's the clause from the SQL Server End User
License Agreement (EULA):
e. Benchmark Testing. You may not disclose the results of
any benchmark test of either the Server Software or Client
Software to any third party without Microsoft's prior
written approval.
Oracle, Sybase, and Informix each have a similar clause. These
clauses are generically referred to as "DeWitt clauses." David
DeWitt was one of the founders of the Wisconsin Benchmarks,
which were first published in the mid-1980s. At that time, the
Wisconsin Benchmarks published less-than-favorable scores for an
Oracle database, and Oracle wasn't happy with the negative
publicity. Oracle added a clause to its license agreement
forbidding unauthorized benchmarking, and most other vendors
followed suit.
