A bunch of little findings:

  • logging via loguru was stalling with enqueue=True
  • sendfile also can lead to stalls late in the transfer
  • tuning the receiver boosts performance
  • TCP configuration parameters don't help too much but enable fewer connections to saturate a link

@samkumar I'm going to go ahead and merge this. I ended up removing sendfile and defaulting to a larger receiver batch size.
