I started to look at the source code and notice that its utilizing wxPython for a GUI interface. Core committers should run the profiler to find the tight loop.  Likely, its a loop incorporating the GUI event thread.  Is the code busy checking for input from the USB and then checking for events on the event thread?

 


It's not using wxPython. We also regularly check Cura with a profiler. It's not something that's running in a GUI event thread. All of these are kinda the first things you do if something is slow.

As for slowness; It seems to vary greatly from one machine to another. It seems to be some combination of hardware & drivers that cause it, but that makes it freakishly hard to figure out what the hell is causing it.

    Cura is starting in 25 seconds, it's not so bad but longer than other software

     

    And windows is starting in 22 seconds

    here are the system informations I have presently with Cura and Firefox running

     

    For the performance Firefox has the worst effect sometimes, with a lot of windows opened in firefox, it can reach 500-600K in memory usage
