At LISA 2008, I gave a presentation entitled “How to Stop Hating MySQL: Fixing Common Mistakes and Myths”.
The presentation slides can be downloaded as a PDF at:

View the video online at http://technocation.org/node/646/play or download the 202.5 MB Flash video file (.flv) directly at http://technocation.org/node/646/download.
Here are some notes and links I referred to:

I was going through your slides and they were obvious just an outline for your talk. But, I did have one quick question… you mentioned innodb_file_per_table but it was just a line item. I couldn’t tell if you were pro or anti (or neither). I’ve heard different takes on using this. I know it is nice for saving space if you are doing lots of deletes followed by optimizing, but I’ve also heard that once you get above 200 tables, there is a hit on performance with opening tables. I was hoping you could give your opinion on when to use or not use innodb_file_per_table. Thanks.
Tom — I’ve added the video, so you (and everyone else) can get the full information. The short version is that using innodb_file_per_table can help optimize disk usage because each InnoDB table has a file for indexes and data.
As far as opening tables, you can increase the size of table_cache.
