However the most extreme difference came on the cheap Celeron NUC (N2830) where I before could run 1 receiver which just took me under 100% (96-99%), two receivers was only usable if I left the machine as alone as possible (i.e. no VNC or TeamSpeak). But after volk_profile I can run 2 receivers together with VNC and TeamSpeak, and the CPU usage of the python script peaks at 35%... that's a quite big difference

So my general impression is; "why didn't I try this before"

I'll tomorrow try to see if this maybe made it possible also to run the Airspy on 10 MHz which would give some new possibilities.
Is it as simple as running the following? :

sudo apt-get install libvolk1-bin
volk_profile
