Cool. Will give it a shot.
I've changed the compiler flags (and can toss in a few use flags too). Mainly for NAS server, that also runs mediatomb (uPnP media center). I need every last bit of go out of that box when doing live transcoding. (I despise doing it, but the procs are already running, so might as well use them).
Same for desktop. Built new one (dual core athlon x2 2.5Ghz energy efficient model) and it doesn't seem that much peppier than my old setup. But, it's lumping along at 1Ghz most of the time, so not such a fair comparison. Would just like to get the "usermarks" (how fast it feels) up a bit. Ricing gentoo as they say:-)
