gforth uses special features of gcc to achieve high speed.

Actually the way that Gforth was built for Debian, even optimizations
that you don't have to turn on are disabled, in particular, dynamic
superinstructions.  This causes Gforth to drop down in the CPU time
rank, but it helps in the memory consumption rank.

To give you an idea of how much this can hurt, here are the standard
Gforth benchmark numbers for 0.6.2 on a 2.26GHz Pentium 4:

siev  bubble  matrix  fib
0.23  0.28    0.19    0.34  gcc-2.95.1; gforth-0.6.2 --enable-force-reg
0.79  1.01    1.11    1.14  Debian gforth 0.6.2-4
