New optional argument to jt9: -w patience
Default is patience = 1
Example timing measurements for 130610_2343.wav:
patience plan execute
(s) (s)
-----------------------------------------------
0 0.01 1.25 FFTW_ESTIMATE
1 0.69 1.25 FFTW_ESTIMATE_PATIENT
2 16.97 1.15 FFTW_MEASURE
3 390.88 1.15 FFTW_PATIENT
Conclusions, consistent with expectation based on past experience
with similar FFTs:
- First decode (in each mode) with patience = 2 is slow.
- Speed advantage of patience = 2 is small but measurable.
- No measurable advantage in using patience > 2.
Present mainwindow.cpp has "-w 1" hard-wired.
