In my timings, it's about 6 times. See
<http://www.complang.tuwien.ac.at/forth/appbench/Results.eps>.
Did VFX become faster since then? Alternatively, maybe Gforth runs
slower on your setup.

On the other benchmarks I saw a factor of <2 (lexex), <2.8 (fcp), <4
of VFX over gforth-fast.

Why did you look at appbench-1.1. appbench-1.2 was released in 2010,
and the generic link
<http://www.complang.tuwien.ac.at/forth/appbench.zip> points to it.

I have not noticed it caching something in a file. Concerning caching
in RAM, given that proper use of appbench means that you start the
Forth system and the application from scratch, any caching there does
not matter.

There used to be some call size dependency in some version of
brainless, but IIRC I have not noticed it in the version that's in
appbench (and I have run appbench on both 32-bit and 64-bit Gforth
systems).

Just define
: key? false ;
in the iforth setup file (Gforth does that to work around a problem
with 0.7.0's KEY?).

I don't remember any issues with 32-bit and 64-bit Gforth, but then I
don't remember whether I compared the results.
But nice to see that appbench is used for its intended purpose.
BTW, I only managed to run benchgc and cd16sim on iforth-2.1. If you
have a setup file for iforth that makes more benchmarks run on iForth,
I would appreciate it.
