I use PostgreSQL a lot but these benchmarking results surprise me. MySQL is often much faster than PostgreSQL and SQLLite is several times faster than MySQL.
What matters to me is how fast they work with Python, or in particular Zope. I need to make my own benchmark of MySQL and PostgreSQL with Zope and all the various database adapters.
The reason I moved from MySQL to PostgreSQL was partly because PostgreSQL has more enterprise features and that my colleges use PostgreSQL. But I suspect that for many of my projects I never even use these features.
Then I also found this from a Zope mailing list:
>The speed comparisions with PostgreSQL are very much an apples vs. fish
>sort of thing: the pgsql server was not tuned at all, and does a whole
>lot more that was never tested, such as multi-user writer access.
