You've got 8 threads to work with on that processor.
Are you doing JT9 or on of the MSK protocols? They will try and multi-thread.
I think you may want to turn off all threading for WSJT-X by setting
OMP_NUM_THREADS=1 as a starting point and see how it behaves for you.
You should also try running SDR at real-time priority. The other settings
really don't do much when threading starts thrashing.

Hello Bill-
Thanks for the reply.I have the FLEX 6700 and run 8 instances most of the
time.The decoding process [8 instances] is a load for even the most powerful
CPUs.Especially when every band has activity.I have the i7 4790 4.0 GHz
processor which does well but would like to minimize processing where
possible.Have been using a RAM Disk to keep the I/O in memory. When the
decoding processes kicks off it does stall SmartSDR [for a second] even when
JT9.exe processes are at "Below Normal" Priorityand SSDR is "Above Normal"
Priority. Maybe a user preference in config to stop the saving?Do you think
eliminating the .WAV file would help at all?I personally never use Alt + "V"
feature.Thanks for your thoughts.

Hi Bill,
how would you propose that the Alt+V keyboard shortcut should work
without saving a .WAV file at least until the next decode cycle?
Why are the temporary .WAV files, which get deleted around 3/4 of the
way through the subsequent period, a problem for you?
