We’re very excited to see MySQL 5.1.30 make it to GA status and
are very proud of the work that the MySQL engineering team has
done to get MySQL 5.1 out of the door.
Maybe you’ve seen some claims by others in the MySQL community
that MySQL 5.1 runs slower than MySQL 5.0. Maybe you’ve also seen
some claims by others in the MySQL community that MySQL 5.1 runs
faster than MySQL 5.0.
Guess what? They’re both right.
With database or any other hardware/software performance tests,
you’re always going to see different results because there are
*so* many variables that go into the equation.
