:I doubt that that sort of benchmark is going to say an awful lot about the
:performance of the optimisation levels since compiling /usr/sr/usr.sbin is
:going to be affected by disk i/o performance far more than it would be by
:cpu performance. The relative speed differences of the different egcs/libc
:binaries is probably smoothed out by the i/o affects which is why the times
:look so similar.

:Something that is more cpu bound would be a better benchmark for comparing
:the optimisation options.

That test was 100% cpu bound. There was no ( significant ) I/O. I ran
it a few times to build the cache before timing it.
It's no big deal, really. I think the EGCS bandwagon is going to continue
to move forward and PGCS runs on top of it, so moving to EGCS puts FreeBSD
in a better position in the long term.
