I have seen various lists of benchmarks of C vs XXX. Sometimes C
wins, sometimes XXX wins. It depends on what you are doing. Here are
a few numbers for Scheme & C (from the Gabrial suite). Note that
these are old benchmarks and compilers are constantly improving--other
benchmark disclaimers apply. These just happened to be published (see
below) and handy.


[Gambit in absolute seconds, others relative]


Motorola m68000
benchmark Gambit Orbit Liar cc
--------- ------ ----- ---- --
tak 0.14 x1.30 x3.15 x1.71
takl 1.18 x1.53 x1.86 x1.80
triangle 67.83 x0.89 x1.96 x0.83


MIPS R2000
benchmark Gambit Orbit Liar cc scc
--------- ------ ----- ---- -- ---
tak 0.06 x1.17 x2.83 x1.176 x2.00
takl 0.28 x1.14 x2.75 x1.79 x2.36
triangle 15.41 x1.02 x2.60 x0.85 x1.77
