Last time I tried autotune I couldn't get it to work on FreeBSD, and it tuned a minimum of parameters. For example, it didn't touch checkpoint_segments, which is pretty essential to tune on a higher-end server. Not saying it wouldn't be a good place to start, but I also don't think it's a replacement for a built-in tuning tool. -- Jim C.
