Interesting concept but no thanks. I appreciate what you have done but I wouldn't install an unsigned Go binary with no available source to tune my servers, although probably it is based on their Github's repositories [0].
Whoops. Didn't indent this to get out. But Autotune doesn't actually change any settings. It just recommends changes and it is up to the admin to change them. It's more of a tuning assistant at present.
