Created attachment 35182 [details] screept itself I've been trying to write script (see speed.py) that shows ammount of data transmitted in pipe, and decided to toy with new fcntl F_SETPIPE_SZ. I've tried to run it on 2 machines with the same result (see call_stack.txt). cat /dev/random | python3 ./speed.py > /dev/null
