Bookmarked! This will be useful to me soon for something I'm working on.
I haven't read all the slides yet but one thing I was wondering was if you ever found any significant performance increases from kernel build options. In my Gentoo days when I would play around with build flags I would change kernel Makefile to use -O3 and apply a patch for -march=native. In hindsight, looking at some Phoronix benchmarks it appears this is actually harmful to a number of workloads. Curious if you ever found any cases otherwise.
