Of course now that I don't have Ultrix boxes handy I just run the
Ultrix C compiler (really the MIPS C compiler, and an ancestor to
the DEC/Compaq Alpha C compiler I think) under Ultrix emulation on
my pmaxen. :-)
Even compute bound programs were a percent or two faster running under
NetBSD than Ultrix - maybe less time spent in the kernel during clock
interupts or something? And this was back in the 1.4ish days (well
before page coloring, which doesn't affect MIPS CPUs anyway).
