90ms for me. My fiber connection is excellent and there is no jitter--fly.io's nearest POP is just far away. You mentioned game streaming so I'll mention that GeForce Now's nearest data center is 30ms away (which is actually fine). Who is getting 6ms RTT to a data center from their house, even in the USA?
More relevantly... who wants to architect a web app to have tight latency requirements like this, when you could simply not do that? GeForce Now does it because there's no other way. As a web developer you have options.
