If a comparison in speed is to be made, we need somebody who cares about Factor
to write the Factor code.
I think Factor is faster than other dynamic-OOP languages (R, Python, Ruby,
etc.). Realistically however, no dynamic-OOP language is very fast. Having
tagged data and garbage-collection is just inherently slow.
Dynamic-OOP languages are primarily useful in regard to the code-libraries
available. R or Python may be very slow, but they do have a lot of
code-libraries available, especially for displaying data. I could write my
programs that require speed in Forth and have them dump the raw data into a
file, then use one of these languages to display the data graphically. Right
now I display the data in the LowDraw.4th program, but it is just a text table
--- this doesn't look very professional.
I mostly posted this challenge to find out if Factor is faster than SwiftForth.
I don't think Factor is going to be anywhere near VFX for speed. SwiftForth is
very inefficient though --- it would be somewhat amusing if a dynamic-OOP
language generated faster code than SwiftForth.
Anyway --- benchmark challenges like this aren't very interesting, especially
when the result is a foregone conclusion --- I just posted it because I was
curious.

Hi Hugh,
Are you planning on implementing your program in Factor for comparison?
You can look over our statistics libraries here:

Best,
John.
