So I'm up just before 5:30am. Why? David Filo paged me because some database servers was pegged on CPU. I investigate. I find a couple of horribly un-optimized queries. They were doing full table scans due to lack of indexes. Even though the tables are essentially in RAM, that really CPU intensive, 'cause all the rows needed to examined.

The moral of the story: Optimize your SQL before running it on my servers and telling the whole world to look at it.

Grr. I guess I'm gonna be up for a while.

John, you have the most difficult blog to read. I'm loving your talk about 10.2, since I recently upgraded myself and have been out of the MacBigot loop for a few years. So your info is something I'm very interested in. But I can't stop looking at those women!

I'm not complaining, BTW. Just sharing. :D

How does SQL Server stack up against MySQL. I know I like the graphical tools for Microsoft products, but how is performance (speed) on the MySQL platform? Comparable?
