Either starlink has vastly improved, or the test is way off in this case.

Dave and Luis,
Do you know if any of these tools are using ~random payloads, to defeat
compression?
UDPST has a CLI option:
(m)-X Randomize datagram payload (else zeroes)
When I used this option testing shipboard satellite access, download was about
115kbps.

Hi Sebastien,
You make a good point. What I did was issue a warning if the tool found it was
being CPU limited vs i/o limited. This indicates the i/o test likely is
inaccurate from an i/o perspective, and the results are suspect. It does this
crudely by comparing the cpu thread doing stats aga

We in test & measurement use that in our internal telemetry. The TSF of
a Wifi device only needs frequency-sync for some things typically

Let me start by saying that I have not been intimately involved with the

Al,
I am not aware of the payload generation.

Hi RR,
Thanks for the detailed response below, since my point is somewhat orthogonal I
opted for top-posting.
Let me take a step back here and rephrase, synchronising clocks within an
acceptable range to be useful is not rocket science nor witchcraft. For

Hi RR,
I believe quality GPS chips compensate for relativity in pulse per
second which is needed to get position accuracy.
