Free advice on your my.cnf
+3 Vote Up -0Vote Down

Today, while on IRC in #pentaho I came across a discussion and a published my.cnf. In this configuration I found some grossly incorrect values for per session buffers (see below).

It doesn’t take a MySQL expert to spot the issues, however there is plenty of bad information available on the Internet and developers not knowing MySQL well can easily be mislead. This has spurred me to create a program to rid the world of bad MySQL configuration. While my task is potential infinite, it will enable me to give back and hopefully do a small amount of good. You never know, saving those CPU cycles may save energy and help the planet.

Stay tuned for more details of my program.
