[erlang-questions] Erlang distribution links don't fully utilise available resources - OTP 22.0.2 - Why?

[Gerhard Lazu]

https://github.com/erlang/otp/pull/2291 is an improvement for larger
payloads, not so much for smaller ones.

60 KB - 13.6 Gbit/s (down from 14.4 Gbit/s)
120 KB - 12.8 Gbit/s (down from 14.4 Gbit/s)
10MB - 8.8 Gbit/s (up from 7.6 Gbit/s)
100MB - 5.8 Gbit/s (up from 4.3 Gbit/s)

This is OTP 22.0.2

https://grafana.gcp.rabbitmq.com/dashboard/snapshot/8yxY61o140gvAKXFthgIVCes2oW2Owa7

Will try https://github.com/erlang/otp/pull/2293 tomorrow
