No way, scanning tickets is slow because it rarely works seamlessly. It's pretty standard to stand there for a few seconds moving your phone back and forth and/or rotating it. Or when one person has all the tickets for their party and has to scroll to the next one between scans.
I think maybe 4-15 seconds between scans per scanner, at best.
Not at all, I was imagining over speccing the system.
E.g. this weekend I went to a show at a 70,000 seat arena. Knowing from experience, there are 4 entrances. This time there were 10 people scanning tickets at the gates I entered. Friends reported the same at the one they came in.
5 RPS per scanner is obviously overkill, but if those 10 at one gate were linked to a hub that could issue 5 RPS I would call that adequate, if barely.
If all 4 gate areas were linked centrally to a system that could do 5 RPS, well, actually, that might explain the throughput I experienced getting through lol
Even at huge venues i dont expect requests would be over 5 rps
