Hi All,With help from Leigh, I have been able to take the CPU usage down from 14% to 6% on each instance of fldigi. The tricks are:
1) Set to use linear interpolation instead of medium sync interpolator. (from 14% down to 8%)
2) Check slow CPU. (from 8% down to 7%)3) On the waterfall in the main window, click on normal until it is paused. (from 7% down to 6%)
This is using a 96KHz sound card.Perhaps it would help to have all these optimizations in one area, or something so you can know what to do to make fldigi use less CPU.

Hi Everyone,I've been using fldigi to spot PSK31 signals on our websdr server. <http://outside.wallawalla.edu:8901/> I have been using jack to feed the audio to websdr and to sdr-core (DttSP) and then on to fldigi. I would like to run more instances of fldigi to spot for more bands, but the load is getting a bit heavy for the CPU to keep up with. The instances of fldigi are the biggest CPU hogs and NX which I was using because I need X to use fldigi is sometimes also a big CPU user. What I think I want is the PSK spotting engine of fldigi running without all the GUI and from the command line. What is the best way to address these issues?Thanks & 73, Rob KL7NA -- Rob Frohne, Ph.D., P.E. E.F.
