Hi,

I also did some benchmarking for the gForth interpreter when I ported
the package.  The results are part of the Benchres file from gForth CVS.

 4.25  5.10   2.82  4.84  0.7.0-20100807--dynamic; Ingenic XBurst Jz4720 336MHz; gcc-4.3.3 (OpenWrt-xburst Backfire 10.03)

The first 4 numbers are execution times for 4 small benchmarks.  For
comparison, some numbers for other systems:

 1.760 2.120  1.016 2.104 0.7.0-20100807; VIA C7 800MHz; gcc-4.3.2 (Debian 4.3.2-1.1)
 0.264 0.380  0.116 0.432 0.7.0; K8 2.2Ghz (Athlon 64 X2 4400+); gcc-3.3.6 (Debian 1:3.3.6-15)
 0.160 0.236  0.072 0.248 0.7.0; Core 2 3GHz (Xeon 5160); gcc-3.4.6 (Debian 3.4.6-5)

Cycle for cycle the Xburst does about as well as a VIA C7 (as long as
the benchmarks fits in the i-cache).  So looks pretty good to me.

cheers,

David
