Hi
I have a system that was running fine on the last release .
It uses the serial module in Python3
When I use minicom cpu usage stays fine.
When I use my Python Script as soon as I open the serial port either /dev/ttyUSB0 or /dev/serial0 Cpu usage goes up to the 90% area and stays there .. cpu temp then goes up to 85 degrees..
Everything seems to work fine!
On the old release cpy hovers around 15%!!!

What could be causing this??
