There is delay from the instrument into the pc followed by delay from the pc to the router then from the router to the first step to the ISP and this goes on to every router on every hop. Sometimes a connection can have multiple parallel paths allowing packets of data to go down different paths which may make things faster. However once packets reach the end router they must be realigned into the original order.

All of this can take time. Even on a Gigabit service each bit follows the one ahead therefore there must be a little latency even assuming no errors or retransmission.

A speed test on my link for example shows a ping response 40ms to a server 100 or so Km away on a link that delivers 50Mbits. Since retiring I don’t handle this sort of stuff anymore.

There are ways to fudge it but unless Einstein was wrong there are limitations to speed. The limitation will result in delay (or if you prefer Latency).
