What are you using as TCP congestion controller? BBR should provide better utilization on long pipes (e.g. transoceanic transfers if stuff isn't geo-replicated). Totally anecdotal, but it helped me FTPing data from the US to europe.

Yev here -> This question's beyond me, lemme see if I can get a dev on the line :D

*Edit - sounds like BBR is used in some of the environment!
