Seriously, I get that it's possible to go off the deep end over optimizing, but that site is way off the deep end in the opposite direction.
- _arvin 8y agoI'm sure it was just poking fun. We can't be kernel ricers and get mad when people make fun of it. CFLAGS matter! lol One thing I will say, compiling your own has many benefits, as all the distribution kernels use Generic x86-64 and miss out on all the Intel/AMD optimizations. For example, just by switching from "Generic-x86-64" to "Core 2 or newer" in Processor type and features -> Processor family in kernel config, adds these 5 optimizations: CONFIG_X86_INTERNODE_CACHE_SHIFT=6 CONFIG_X86_L1_CACHE_SHIFT=6 CONFIG_X86_INTEL_USERCOPY=y CONFIG_X86_USE_PPRO_CHECKSUM=y CONFIG_X86_P6_NOP=y You can say it's pulling hairs, but hey, that's what I want. Not many people have the time, know-how, run Linux, etc. to be able to make these optimizations.
