LimeSDR mini speed test on several different systems

I ran the LimeSDR Mini running on several systems using SdrGlut and CubicSDR to test its speed. On MacOS Mojave, Ubuntu 18.04 and Windows 10, SgrGlut manages to run the LimeSDR Mini at Full Speed (40 MSPS). On the PI 4, SdrGult tops out at 18 MSPS. I make a video -

On MacOS Mojave and Ubuntu 18.04, CubicSDR manages 4 MSPS. On Window 10 and the Pi 4, CubicSDR could only do 2 MSPS. Clearly, there is some problem with CubicSDR 0.2.5 - it should do much better. Here is the video -

The programs can be found at -

Interesting and thanks for sharing! Maybe worth logging an issue on the CubicSDR repo?

Also SdrGlut looks like a pretty cool minimal dependency SDR :slight_smile:

I reported the problem. It appears that an error was introduced some where between versions 0.2.3 and 0.2.5.

The problem has be fixed in version CubicSDR 0.2.6a, but you have to build everything from source -
