The contest evaluated the solutions sent in by whoever wanted to participate. This doesn't prove anything, except that the MySQL marketing department is exceptionally slow.

There was just one submission for PostgreSQL made by one guy who didn't manage to finish it (c't says connection pooling didn't work). See: http://archives.postgresql.org/pgsql-advocacy/2006-06/msg00052.php MySQL's winning submission was by a team from MySQL AB. Enough said... Bye, Chris.

Looks like it was a design contest not a benchmark to me. Surprise, surprise, the team that personally designs a DBMS has the best performing DBMS. The second place winner, Alexander Burger, is the author of the solution he used: Pico LISP. The third place team, MonetDB, used their solution, MonetDB. The results tell me that people who write databases can write good apps that use those same databases.

I'm wondering if the source code is available. My guess is it was full of MySQLisms and the postgresql "port" was written without indexes, no transactions, and relied on running dozens of queries that postgresql could have more efficiently done in one query or in one transaction at least. I wonder if one couldn't get ahold of the code and "fix it" to see what postgresql could actually do. We have the same problem at work. RT is a great little program that supports several database backends. But it's dumbed down to make MySQL 3.23 happy and fast, so it's kinda a dog on PostgreSQL, even though it's ultra stable. Seems the newest release is finally catching up on PostgreSQL.

Now, this article really s**ks! First of all, the original contest was specifically not only about performance. And the MySQL team did a whole lot of dirty tricks (i.e. using memcached) to push their solution. I am the one who has written he only PostgreSQL entry, for which I'm still sorry and ashamed, because it performs so poorly. I just didn't have much spare time to spend, but thought I'd send it in anyway. One of the reasons it did not perform well was, that I simply have forgotten to enable connection pooling. Another entry using Perl and PostgreSQL from somebody who put a lot more time and effort into it was disqualified because the benchmarker claimed the files came in to late. While the author of the PostgreSQL solution claims the wrong ZIP archive has been used. Besides, was quite a simple database test, not too complicated queries, very few stored procedures. No views, no triggers, no 2PC, no nothing. So IMHO it was not even a good test of database extensibility. So this comparison is really just... ah! forget about it! (Just please, next time, let's put a little more effort into such a thing.) Regards Markus

Was this all the same basic task implemented by different teams then? Can we see the code? hack it? I'm sure someone here could help out. I don't care about the contest, but it would be nice to be able to put out a version that could compete with MySQL's.

Yes, I see that now. I thought it was one version of the same app pointed at different DBs. I see now that it's not. See my most recent post...

The main db-contest site of the magazine is [1], but it's all german. You'lll find an english translation of the original article, describing the problem to solve in [2]. The contest entries are downloadable on [3]. Mine is the 'bluegap' one. If you want to hack together a high-performance solution based on PostgreSQL I'd start with Alvar C.H. Freude's disqualified entry.

Seems they are fast where it counts... namely getting a team of developers on top of the contest so they come out shining.

Perhaps because PostgreSQL is too busy competing with itself? Is anyone aware of any other open-source project that has added so many new features in the past year? -M

I *think* Robert's point is that a paid advocate may have actually been
looking for this type of thing to come up and would help organize an effort.

FWIW it was mentioned and discussed on the german postgresql list.

Right... these types of things come up all the time, whether they be
benchmarks, contests, tutorials, or just general application support, and all
of the commercial database companies (ie. oracle, ibm, ms, mysql) have people
on staff to point at these tasks. The community has been good about full
time developers working on core, but seems to overlook all of the other areas
that you can point a paid developer that will increase adoption.
