Yes.
If 1M users are online, there are roughly 1M open connections.
But here’s the important part:
It’s not 1M threads.
It’s 1M lightweight, event-driven connections.
Modern systems (like WhatsApp) use async, non-blocking I/O.
So one server can handle thousands of open sockets without creating thousands of threads.
Also:
•Connections are distributed across many servers
•Load balancers spread traffic
•Each server handles a manageable slice
So it’s not:
1 server ↔ 1M users
It’s more like:
Hundreds (or thousands) of servers
each handling a few thousand persistent connections.
So yes, 1M users ≈ 1M open connections.
But the architecture is built exactly for that.
@Mrbankstips like GPS requires relativity corrections; nuclear energy follows from mass–energy equivalence. That foundational shift changing the framework scientists use to explain the universe
@Mrbankstips WTF are you saying
There were both great in their domains but Einstein rewrote the rules that physics is built on. His theories changed our understanding of space, time, energy and gravity, gave precise predictions and enabled technologies we rely on today
