benchmark 1.4 and results

[Francesco Potorti`]

There is a new version (bm 1.4) of the octave benchmark at
ftp://fly.cnuce.cnr.it/pub/benchmark.m.  The tests are the same as
before, only some minor changes have been made, and the Sun Sparc 10
is now the reference machine, as it is the platform used for Spec95
numbers, as Rick Niles says.

I collected the numbers some of you sent to me and organised them in a
table.  The numbers referred to Sparc2, I just scaled them in order to
match the new reference, which is Sparc 10.

Unfortunely I miss some interesting platforms, for which I have
numbers only for the very first version of the benchmark, which are
not scalable to the new tests.  Here are the missing platforms:

Evan Thomas <address@hidden>
  Linux/Pentium 133
Jarle Brinchmann <address@hidden>
  Linux/486dx4-100
John L Daschbach <address@hidden>
  Linux/Pentium 120
  OS2/486
  IBMrisc6000

And here is the table of results:
