Thanks to Pearu for these benchmarks.
I just ran some linalg2 benchmarks on my ATHLON 1.1 GHz processor (gcc-2.96,
Mandrake -8.2). It would be interesting to see what others are getting.
>>> linalg2.basic.test()

Finding matrix determinant
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | Numeric | scipy | Numeric
20 | 0.26 | 0.50 | 0.25 | 0.58 (secs for 2000 calls)
100 | 0.45 | 2.01 | 0.43 | 2.30 (secs for 300 calls)
500 | 0.50 | 2.92 | 0.48 | 3.06 (secs for 4 calls)
.
Solving system of linear equations
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | Numeric | scipy | Numeric
20 | 0.40 | 0.43 | 0.40 | 0.50 (secs for 2000 calls)
100 | 0.50 | 1.79 | 0.51 | 2.25 (secs for 300 calls)
500 | 0.49 | 2.98 | 0.48 | 3.15 (secs for 4 calls)
.
Finding matrix inverse
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | Numeric | scipy | Numeric
20 | 0.52 | 0.89 | 0.51 | 0.96 (secs for 2000 calls)
100 | 1.18 | 5.73 | 1.18 | 6.01 (secs for 300 calls)
500 | 1.31 | 15.34 | 1.30 | 15.82 (secs for 4 calls)
.
Look at that speed up.... fantastic.
