Hello All
Thanks BAS for your config.toml, which I implemented this night at Rigi Scheidegg.
Attached a picture with the CPU Load with fft_threads=1 and only one user connected.
Should I use more fft_threads with 8 CPUs (Intel i7-6700 @ 3.4 GHz x 8)

If you use opencl the fft threads wont change anything. Only if you use the CPU to do the FFT.

OK, thank you for this information :-)

Your Intel doesn't have 8 cores, just 4, but it should be able to handle 2 threads per core....however, this doesn't always work. It has been proven many times that realtime applications are hindered by this multi-thread setting.
I would turn MT off in the BIOS and let it run as 4-real CPU's.

See info of your CPU.
Also, with OpenCL in use more then 1 fft-thread is useless, you have understand that with OpenCL only webserver-threads are important, this is a different setting and has a different purpose.
Good NEWS
Since I use the config.toml from BAS with fft_threads=1 etc. my PhantomSDR-Plus at Rigi was not crashed anymore - The PhantomSDR is up and running since 3 days :-)
I hope it stays that way.
Set it to 2.....it's better.
I do not know why, but seems to be more stable.
