I have no idea what they do but indeed the Arduino IDE has shown ridiculous compile times on some Windows systems… I’m not entirely sure why. They should be using all available cores (see e.g. https://github.com/arduino/Arduino/issues/8589). Maybe process affinity is not set to all CPUs?
Hello, in my case with a more modest PC with i3 in W10 it is taking about 24 minutes each compilation with Arduino 1.8.5. I really love Edge Impulse but it drives me crazy having to use Arduino on W10. I don’t know how to solve it any other way.
@tototek Yeah I completely agree! I have no idea what’s happening here but I remember having similar issues with compiling Mbed OS on Windows. Users have been reporting that the Arduino online IDE works much better.
