    64 MySQL Technical Reference for Version 4.0.3 Because of this we can't put any trust in this benchmark either.  :( Over time things also change and the preceding benchmarks are not that relevant anymore. MySQL Server now has a couple of di erent table handlers with di erent speed/concurrency tradeo s. See Chapter 7 [Table types], page 494. It would be interesting to see how the above tests would run with the di erent transactional table types in MySQL Server.  PostgreSQL has, of course, also got new features since the test was made.  As these tests are not publicly available there is no way for us to know how the database would perform in the same tests today. Conclusion: The only benchmarks that exist today that anyone can download and run against MySQL Server and PostgreSQL are the MySQL benchmarks.  We here at MySQL AB believe that Open Source  databases should be tested with  Open Source  tools!  This is the only way to ensure that no one does tests that nobody can reproduce and use this to claim that one database is better than another.  Without knowing all the facts it's impossible to answer the claims of the tester. The thing we nd strange is that every test we have seen about PostgreSQL, that is impos- sible to reproduce, claims that PostgreSQL is better in most cases while our tests, which anyone can reproduce, clearly show otherwise.  With this we don't want to say that Post- greSQL isn't good at many things (it is!)  or that it isn't faster than MySQL Server under certain conditions.  We would just like to see a fair test where PostgreSQL performs very well, so that we could get some friendly competition going! For more information about our benchmark suite, see Section 5.1.4 [MySQL Benchmarks], page 336. We are working on an even better benchmark suite, including multi-user tests, and a better documentation of what the individual tests really do and how to add more tests to the suite.
