I don’t like the heat. I hate being hot. Always have. I’m the guy who will leave the windows open when others have already turned on the furnace.

While the answer to this question is always ’that depends on your hardware and workload’ and involves a lot of iteration between changing a setting and benchmarking, I thought I’d take a moment to point out that once you do manage to dial-in the settings, you should be writing a profile and deploying to your systems for tuned to make use of. Please, for the love of $diety, stop editing sysctl.conf and friends!
