Is that because the 486 has a dedicated floating point coprocessor whereas
the sparc doesn't?

For what its worth, here are some benchmarks I have gathered using some code I wrote
myself.  It shows how many seconds different computers take to complete a benchmark.


About the benchmark.  It is a tcl script which solves cryptograms using a dictionary
and pattern matching.  I tried to always use the same version of tcl interpeter so
results would be more evenly matched.  I chose to use tcl since it can run on any
os/cpu.  Also, this started out as a learning exercise for tcl and not as a benchmark.
However, since it takes such a long time to run, it makes a good benchmark program.

And yet another thing.  When I tested the e450 at work, it was not loaded.  It would
be nice to see the results of an unloaded e450.  It would also be nice to see how long
it takes to perform mulitple tests simultaneously for multiprocessor computers.

Here are the results sorted best to worst in order of seconds to complete
the benchmark:
