kernel compiling
I wanted to try recompiling my kernel with optimizations for my cpu. I've never done it before. I thought I would post here first in case someone knows of a concise how to or has warnings or observations. Thanks.
Compiling is (quite) easy: https://trisquel.info/en/wiki/compiling-gnu-linux-libre-kernel
Configuring the kernel is the hard part. The Gentoo Handbook used to be (and probably still is) a good first documentation on the topic: https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/Kernel#Default:_Manual_configuration (forget about all blocks but those marked with "KERNEL").
