Right! I forgot -pipe, that one's good. Unless you have bad RAM that you're trying to use as little as possible, or some such thing... > Right now I use CFLAGS="-march=athlon-xp -O2 -pipe > -fomit-frame-pointer". -O3 isn't worth it.

Yeah, the larger binaries just cause more disk access (the real choking point) and can cause some overflow out of cache with certain processors. It's best to enable individual O3-enabled flags as you need, though you really shouldn't need. Tom
