[B]you can always go back and recompile anything that doesn't work
it's as easy as doing it the first time only different
you start with
Yes you can recompile and i had to do it under freebsd, but i had to track myself which ports i had to recompile to avoid recompiling lots of dependencies...
yes we already know about the racist website and have noticed how some people who have mental problems have to engage in bizarre blaiming activities directed at certain groups in order to feel good about themselves.
i can't really say that it relavent to our discussion.
funroll-loops is a compiler technique whereby loops that have a determinate size are unrolled so the loop data can be moved to and from memory as part of a single cache line prevent mmu cache thrashing.
NORTH if you thing gcc -funroll-loops is not usefull in this way then please provide us with valgrind data to back up your assertion or kindly keep your bizarre opinions to yourself.
I don't really see how the site is racist, but I can't say I've read every word on it either. It's a joke, lighten up.
It's relevant because it's a parody of the mindset that a lot of Gentoo users display, claiming that compiling everything from scratch will make the system magically faster. Sure there are some benefits that can be had when you're not compiling packages to support the lowest common denominator, but IMO it's mostly a waste of time. I'd rather use precompiled pacakges that get real QA done on them.
