  I usually use a gcc compile (with -O3 -ffast-math) but I have also tried
the cc compile (with -fast -xarch=v9). The latter is a bit faster than
the former (something like 5%), but the binary is almost twice as big
(that's why I use the gcc compile as I have a limited quota).

  I'm not saying that "my" Sun is "so fast". I'm just saying that it's
faster than a P-II 350MHz (which is quite good as this UltraSparc has
only a 333MHz processor).
  It would be quite unfair to compare it with an Athlon 1.2GHz as neither
the MHz amount nor the architecture are at the same level (this computer
is about 2 or 3 years old).
