- I have a lot of experience running the same lisp program both on a IIfx (36Mb)
- under MCL and on a Sparc II (64Mb) under UNIX/Franz Allegro 4.1. The Sparc can
- only consistently produce a factor of 2 speedup. (Once in a while 3x but
- never more and sometimes only 1.5x). This is over many different types of
- cpu-bound application. When I start doing disk i/o, the IIfx slows somewhat
- but that probably reflects more about the IIfx disk i/o architecture
- than the lisp speeds.
