[Octave-bug-tracker] [bug #60928] Performance of sort unexpectedly slow for DIM=2

[Rik]

Update of bug #60928 (project octave):

                  Status:         Patch Submitted => Fixed

Follow-up Comment #19:

I ran 100 tests (to get above the central limit theorem) for sorting along the
first dimension with the special case code and without.

Results:


special case: 98 +/- 2 milliseconds
regular case: 109 +/- 3 milliseconds


Percentage difference from 98 to 109 is 11% slowdown so it appears to be worth
it to have the special case.

I checked in the patch.  Thanks to the original bug reporter for finding this
odd behavior and drawing attention to it.
