Hi Mike, in my case i have to optimize running multiple tasks parallely but they all have changes to the user interface. How should i proceed in that case.
Right now my code hangs sometimes and shows as "Not responding". How do i get to know which tasks are clashing? Thanks

Is there any advantage or scenario where using Python's multiprocessing or threading library is better suited than PyQt's QThreadPool?

I'm interested in updating a Matplotlib or PyQtGraph figure real-time via a serial-port.. passing the data from a separate process or thread, to the GUI via pipe or queue?
