This may be more a Tor than a Whonix-related question.
I had the following thought lately: is it possible to fingerprint Tor users by monitoring their internet speed?
Example: let’s take a 10 mbit/s vs a 100 mbit/s internet speed. Will the 100 mbit/s connection reach higher speed on Tor? Or does the Tor network have built-in speed limitations regardless of the client’s own internet connection speed?
If not, can the clients be fingerprinted by looking at their speed connection? I.e. if a Tor user is showing constant higher speeds, can his internet speed connection be inferred, and can it be used to single him out (as in: some Tor circuits at specific times with this specific entry guard are constantly showing higher speeds than other circuits, therefore it is probably the same user/set of users).
It may be a very noobish question, but it got me a bit confused…
