Slow Performance on Linux

[Evan Thomas]

Here are the the benchmarks results from my machines using Francesco
Potorti's benchmark and the lsode example from the manual.

Sun SPARC Station 2:
test #1          0.74125 +/- 2.7% (10 runs)
test #2          3.99875 +/- 0.5% (10 runs)
test #3           8.8825 +/- 4.0% (10 runs)

Linux/Pentium 133:
test #1         0.161429 +/- 4.7% (10 runs)
test #2         0.844286 +/- 1.9% (10 runs)
test #3             1.69 +/- 0.0% (10 runs)

About what everyone expects. 

However that still leaves me with my orginal problem which is why *my*
ODEs are so slow. 
  - does anyone else experience the same problem with the original
equations on linux?
  - could it be a performance bug in a linux library?
  - could it be a performance bug in #ifdef'ed octave code?
  - what libraries is octave linked against?
  - if other people don't have the orginal problem, what version of the        
    libraries are they using?
  - have I done something wrong (my orginal theory)?

As it stands solving the systems I want to solve on the pentium is not a
practicle proposition. I suppose I could try to profile octave myself...

Thanks for the interest shown so far in my problem,
Evan.
