You're asking questions that really cover a very wide area.

traceroute can take a snapshot of point-to-point connectivity at each
moment you run it, with the timings in each hop expressed in

Note that the Internet is by definition transient and routes around
trouble, so that the path of a packet is *very* subject to change from
one minute to the next, even though that might not always happen.

Screen responsiveness is an entirely different issue.

I know of no way to measure that other than to sit with a stopwatch in
