IIRC was solar who said some time ago that executables are mmapped before the

I'm still convinced this is untrue (apart from disk space). Debug
symbols are not part of the executable view. The kernel & loader ma

tmpfs has miserable performance when larger than RAM iirc

I was wondering if there are any sane ways to optimize the performance
of a Gentoo system.
Overoptimization (the well known "-O9 -fomgomg" CFLAGS etc.) tends to
