As you can see --disable-http2 seemed to really have unlocked some bottleneck with increasing checkers really helping.

Ah, this is because of this Go issue x/net/http2: client can't fully utilize network resource · Issue #37373 · golang/go · GitHub

Again, can't get above ~6GiB/s

This is the figure that you got for this experiment

I did this across 16 synchronized panes of tmux:

rclone check --download GCSTakeout:takeout-export-HASH GCSTakeout:takeout-export-HASH --progress

I was able to get to ~6GiB/s with ~50% CPU Utilization:

Maybe you have arrived at the limits of the server?

When you do your test with --disable-http2 which seems to be the major improvement, what does CPU utilization look like?
