As you can see below, VFX is 10 times faster than Gforth, and almost 10
times faster than gforth-fast, on cd16sim.
On the other benchmarks that I have tested the speed range is more like
a factor of 6 (a car versus a bicycle).
While taking a closer look at appbench-1.1 I noticed a few interesting
things.
1a) brainless contains some kind of cache. It's playing improves when you
run the benchmark a few times. The final speed figures are shown.
1b) In brainless, all Forths do about 22,000 nodes and 30,000 evals,
except iForth64, which does 34,000 nodes and 48,000 evals. I couldn't
find the reason for this (in limited time), but my hunch is that
brainless uses bit/cell or cell in a special way.
2) fcp ran very slowly on iForth. I found that KEY? is used in a tight
inner loop. In iForth, KEY? calls usleep() to yield to background
processes. This probably invalidates a standard fcp for comparison
purposes.
3) lexex is very slow on iForth64, and iForth32 is much faster than
iForth64. Again, I could not really find what is causing this.
Lexec defines 64-bit sets when bits/cell is 64, but the total number
of cells in a set is proportionally smaller.
Can anybody come up with a reason for 1b) or 3)?
