I am connecting to a debian system over a serial connection and streaming real time data from a pressure sensor. Originally I used:python3.6 pressure_streamer.pyThe data is being produced at 32.1kB/s and it needs to be buffered in case the reader is busy. I can add a buffer with the pv command:python3.6 pressure_streamer.py | pv --quiet --buffer-size 10MWith pv the data appears bunched up into 8k writes in the steady state. This adds ~250ms of latency.Is there a way to buffer which adds less latency? 
How can I buffer a pipe with minimal added latency?
shell;python3;pv
