Executor got slower?  That is most puzzling!  Which tests?  Is it
consistently reproducible?

OK, but what type of machine do you have?

Speedometer has definitely been useful to us!  Speedometer should be
available on numerous ftp sites, so there shouldn't be any need for
you to upload it anywhere.  Users should beware that Executor has
problems with Speedometer 4.0.

The synthetic CPU paper we posted to the net has Executor's
Speedometer CPU emulation numbers at the end.  In case you missed it,
here they are again.  These numbers were computed with Executor/DOS,
but the CPU emulator is the same for all 80x86 Executors.  By
definition, a Mac Classic scores 1.0 in all benchmarks:

In fairness, our graphics aren't nearly as fast as our CPU emulation,
especially when we have to go through X windows or NEXTSTEP.
