I don’t have my Starlink anymore, but I’ve just noticed that at least with
Speedtest screen shots, the bufferbloat seems to be much more under
control. E.g.

https://www.reddit.com/r/Starlink/s/THVeQ3r43D

Hopefully it’s not just an “optimization“ for the test. Maybe Nathan has
had a positive influence in that respect.

I still own the v2 hardware and would love to supports them instead of
Verizon, but if they had a more affordable 50/5 package for $50 which is
what Verizon charges for their 50/5 LTE service I would jump ship and run
some flent tests.

Anybody in this list able to confirm the better bufferbloat results?
