@nichii so have you used gentoo before?
@kura @nichii I gave Gentoo a shot. I actually love it for its documentation that is possibly only 2nd to Arch's. I loved portage. It was very straightforward. Only reason I went back to Arch was the compile times on Gentoo. It took more than a day and a half and was still compiling Firefox... I'd probably use Gentoo if I could find a way to at least mitigate that issue.
@apaperez @nichii get a decent cpu (never had that issue on a modern one). use compiler caches (drastically reduces recompile times). use appropriate gcc flags (more specialized flags, especially on gcc, is faster compile time). check your USE flags (the less you USE, the less to compile). check for distributed compiling (if you have multiple machines. examples are distcc and icecc/icecream).
also, if you change your march or mtune flags (I suggest march over mtune. Read the 2 links there) you should recompile gcc twice.
You run a stage one gcc.
When u compile gcc first, it creates a stage 2 gcc (optimized gcc with generic code gen)
you compile a second time, you get stage 3 (optimized gcc with optimized code gen).
not sure if the ebuild does it on its own now. check the log output if it compiles twice.
