I have an Apple laptop (running Linux, 233 MHz PPC750 with .5 MB L2 cache
66MHz bus).
I find that benchmarks don't reflect the intended use of the computer. For
example, the STREAM bechmark <http://www.cs.virginia.edu/stream/> reported a
modeds 97MB/sec of memory bandwidth. I then tried STREAM with smaller data
sizes and was amazed that if the data could fit in the L2 cache, the bandwidth
trippled. So this architecture rewards good, tight programming. I included my
STREAM runs at the end of this email.
Another 'benchmark' I tried was running the benchmark gforth (GNU Forth)
programs. My laptop performed well against a 450MHz celeron. The results show
that the laptop is a lot slower on one test (.5 the speed), 18% faster on
another and 50% and 25% slower on the last 2.
The architecture of my laptop (due to a slow system bus) rewards using the
cache. This seems to suite may applications. Benchmarks don't seem to reflect
this.
If anyone has any PII or PIII laptops runing Linux, I'd be interesed in their
performance numbers for STREAM and gforth.

Some benchmark results for various combinations of hardware, Gforth version, and Gforth configuration. Unless specified otherwise, the default configurations were used. You can measure your combination with `make bench'. You can find a table comparing Gforth with six interpretive Forth systems in the manual (Section Performance), and a comparison with more systems in http://www.complang.tuwien.ac.at/papers/ertl&maierhofer95.ps.gz.
All times are given in seconds of user time.
