Follow-up Comment #27, bug #29768 (project octave):

The recoding to use m < 16 for the Pade section really speeded things up.  On
the same random test matrix the benchmark timings were:

Elapsed time is 1.554 seconds.
Elapsed time is 0.009721 seconds.
Elapsed time is 2.249 seconds.
Elapsed time is 1.706 seconds.
Elapsed time is 0.7743 seconds.

The Pade section changed from 4.4 seconds to 1.7 seconds.
Overall the code is now just 2.4X longer than the old eigenvalue-based code.
