Even with a crappy DSL connection I haven't routinely seen >70ms latency for years. Modern cable/fiber/LTE/NR connections are all well under 50ms. Even then, we have realtime games with lag compensation that make that connection instant. Your problem sounds like a badly written app, not a tech limitation.

What definition of latency are you using here?

> connections are all well under 50ms This depends entirely upon where you're connecting to, and from. For example, I can't connect to us-east-1 servers with under 50ms of latency, because I'm out in the rural west, and my connections run a thousand miles south before getting on a good east/west backbone. Spikes are not uncommon. > we have realtime games with lag compensation that make that connection instant When the prediction algorithms are correct. When they're not, you start seeing some uncanny behavior that you can't predict or compensate for (dead-on shots missing, actions being rolled back, etc).

Where you live, sure. But I can drive just a couple hours north of San Francisco and lose all cellular connectivity, entirely. In fact I am doing just that tonight and my friend and I have made contingency plans for meeting up at a festival going on in the mountains off the 101, where we expect to have no cell service. I really wish people would set aside their "well it's always worked for me, surely it must work for everyone" attitude, because it is tragically and obnoxiously false.

So now we have to build real-time lag compensation into our dev tools?

I'm in London, my fancy iPhone on 4G is fast enough, yet it averages 100ms latency, as measured by ping. Explain that.

Latency is affected more by geographical location than your local internet connection. If you're in San Francisco connecting to a server in London, it's a physical impossibility to get under ~60 ms, and that's assuming a direct signal going across the surface of the planet at the speed of light. In reality, it's not direct, and there will be at least a couple dozen routers between.

I live in Argentina, anything in the US is at least 150ms away.
