The session at the Boston MySQL User Group was very enjoyable. There was a full room, and the presentation was followed with attention and curiosity.
The slides I used for this presentation include the deck used by Allan Packer and Mikael Ronström at the MySQL Conference 2009, followed by a testimony of my own experience with 5.4.
Here is the final deck: MySQL 5.4 theory and practice
While preparing the slides, I realized that, for the first time, we have a product that allows a painless performance gain. Unlike all the tuning and technological improvements that you can use to improve performance so far, upgrading to MySQL 5.4 is a simple and easy step to a performance gain. It deserves at least some testing, because of the huge difference that it can make.
On May 21, there will be an online presentation by Allan Packer on MySQL 5.4 Benchmarks In-Depth.
