When printing data to Serial at high speed (115200) the Serial Monitor cannot keep up with the board output and CPU performances jump through the roof.

Some work has been done on serial-monitor-rate-limiter branch. This comment could be related. Note, every single character comes with a request to the frontend, as no rate-limiter is configured on the CLI side. This means if you have a println("foo") sketch, you will get f, then o, finally o on the IDE side. Maybe the communication is too chatty between the CLI and the IDE.

I have the same problem. So I just limit it to somewhere around 200ms delay on the main loop() funtion.

OS: Linux(Ubuntu 20.04.3 x86_64)
