No need for alarm .... it's consistent with previous versions of
FreeDV GUI that people have been running since 2012.
Optimisation of the DSP code won't help, as it doesn't appear to be
in the modem/codec/FEC, e.g. running the FreeDV stack from the
command line over 60 second samples:
$ time ./freedv_rx 1600 ~/Desktop/ve9qrp_1600_8010.raw /dev/null
real 0m0.748s
$ time ./freedv_rx 700D ~/Desktop/ve9qrp_700d.wav /dev/null
real 0m0.766s
Perhaps 1% CPU.
It's most likely in the GUI code. If anyone would like to take a
look at this, I'd be interested in the results of profiling and will
happily accept patches to reduce CPU. This is a job anyone with
general C/C++ coding experience could do - you don't need to
understand the DSP.

or rather either that's alot of CPU or the cache is thrashing
Is it using SSD / NEON vector instructions ?
