the Forth Benchmarks have been moved to its own dedicated website at [https://theultimatebenchmark.org|https://theultimatebenchmark.org]
Below is a collection of some Benchmarks for Forth83 systems like VolksForth.
I found most of these benchmarks on [comp.lang.forth|http://groups.google.com/group/comp.lang.forth], [Hans Bzemers|http://thebeezspeaks.blogspot.com/] [4th|http://www.xs4all.nl/~thebeez/4tH/foldtree.html] and Marcel Hendrix [benchmark collection|http://home.iae.nl/users/mhx/monsterbench.html]
