Wow... that's *much* better that I would have guessed. Is the compiler the same for each? > You can't fairly compare compiling a PPC kernel on a PPC box with > compiling an x86 kernel on an x86 box. GCC does more work compiling > for PPC than for x86. I wasn't trying to compare fairly, mostly get the lowest possible compile time.
