The MIPS Performance Brief, version 3.8, contains 15 or so benchmark
values for a variety of machines.  About 8 of the tables include
values for both 4.3bsd cc and gcc1.31 (running on 4.3bsd) for the VAX
780.  Send a snail-mail address to mash@mips.com for a copy.

I once tried to organize an effort to collect gcc vs. cc results on a
variety of machines for our benchmark suite, but I ran out of steam
before I got tapes to the people that volunteered.  Oh well.
