On the majority of x86 or x86_64 hardware there's very little room for across the board gains in performance over otherwise standard cflags. On slightly less 'normal' hardware, like, say, an Atom N270 based netbook with 1GB of ram, however, a few cflags go a *long* way towards having a usable system. My Mini9 shipped with a variant of Ubuntu that's actually built with general optimizations to make it usable on that hardware, and having run the same version of Ubuntu without those optimizations for a day or two on it, the amount of stutter and stalling was almost unbearable. Then, with the help of a desktop (or three) to handle the bulk of the compilation, I moved to Gentoo on it. I hadn't sorted out what cflags would be best, and simply built what I needed to get back to work on it with fairly minimal use flags, and I was rather frustrated to find that it still ran worse than the factory install, once programs had started (though that process was noticeably faster, as it generally is with so much less running in the background). Once I adjusted to the appropriate cflags, the stutter cleared up, things didn't stall frequently, and the system was simply more responsive. I could even watch flash videos full screen without it stuttering, which I'd given up on as a possibility on the system. A vast majority of the gains I saw were simply from clearing away the 80% of Ubuntu's features I have no use for, but when you have a processor that approaches things just a little differently, like an Atom, you really can gain a bit from letting the compiler put things in an order the processor will agree with better. -- Poison [BLX] Joshua M.
