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.
