issues with kivy speed

[Diego Fernando Pedraza Cardenas]

I am currently developing a software with kivy and python, this software needs to be executing many tasks simultaneously all the time (reading sensors, protections, online graphics, events, modbus tcp communication, etc), for this I use threads and while loops, But I'm at a point where the screen is too slow to update the data and move between screens, the truth is that the code currently has more than 50 thousand lines (among all the libraries) and it works well but the interface does not respond as I would like. Do you have any suggestions to optimize the speed of kivy?

Start by profiling your code to understand where time is being spent. Then you can focus your optimizations. 

Rather than running threads all the time and using while loops, you should use the Clock.schedule_interval() to schedule running these background tasks.  

It may make sense to use multiprocessing for some tasks.

only changing the threads for clock.schedule improved in an incredible way, really thank you very much

Thanks for letting me know how it worked out.  😎
