Please note that the Neal Nelson benchmark is meaningless when comparing
machines with different architectures, or when comparing different com-
pilers within the same architecture. It is weighted against machines
using optimizing compilers (including strength reduction, loop unrolling,
and common subexpression elimination), register allocators, branch pre-
diction, and many other modern compiler and architectural enhancements. 

AIM, on the other hand, has proved itself to be quite meaningful, as syn-
thetic benchmarks go.

Anyone who is at all serious about benchmarking should get a copy of John
Mashey's "MIPS Performance Brief," and the MIPS benchmark suite. (Last I
knew, MIPS was giving the suite away for $200, on 9-track mag tape.) I'd
like to see every systems vendor agree to run this under John's super-
vision, and publish the results. Would settle a lot of bar bets. :-) Of
course, I suspect John has more important things to do with his time. :-)
