PostgreSQL first real benchmark has been published:
This publication shows that a properly tuned PostgreSQL is not only as fast or faster than MySQL, but almost as fast as Oracle (since the hardware platforms are different, it’s hard to compare directly). This is something we’ve been saying for the last 2 years, and now we can prove it.
For open source database nuts, this is awesome news. PostgreSQL has had a more mature feature set than MySQL for years, and now they have a faster database to boot. Throw in the far less restrictive BSD license, and I see no reason whatsoever to use MySQL for any serious application.
