A well-tuned my.cnf file can be the difference between a nicely purring database server and one that is crawling like frozen molasses. I present an annotated version of my own my.cnf file here for those interested in specific tuning suggestions for that file.
Do not blindly copy this code block into your my.cnf file - you need to set the path names appropriately for your needs, and in many cases, the default is just fine. On the other hand, I have divided my I/O load between two disk arrays, so I've changed the defaults some.
