Hi Glen, difficult to say:
I have data for freedv_comprx() for FreeDV 1600 (translates to decode 1300 because of use of some bits for data transmission) which does modem decode every 20ms and voice decode very 40ms. On average I have 12.2 ms -> 24.4ms, 2x5ms are the fdmdv_demod part, so decode1300 is 14.4ms. I am using gcc 5.4, O2 mostly (some files have O3 enable, but none of the codec2 files. And I run more or less newest SVN code (codec2-dev 2875) If you run somewhat older code, the numbers you gave have been the performance a few days ago. As David mentioned, we gained about 40% since r2842 (or so). So they could be right.
