Pi Zero for GUI and hardware controls to free more CPU?


#1

Wondering if the title says it all… :slight_smile:
I have a Pi2, a Pi Zero and Pi Zero W…
If they were connected via USB…
Would there be any performance gain (and wifi!) if the GUI was off loaded to the Zero W?

Hi @B00t-eek!
As far as my experience with a RBPi 3 based Zynthian goes: The bottleneck is software like the zynaddsubfx Synthesizer not being multi thread optimized. Having that in mind I would furthermore speculate that the Linux task shoulder should be running the GUI on a different core then the one having a high load from the Synthesizer.
So I guess: The potential performance gain might be to small to justify the amount of work needed for splitting the Zynthain on two devices.
