Or going from ~1ms over a local wired network to ~10ms over a wireless network.

Had a customer performance complaint that boiled down to that, something that should take minutes took hours. Could not reproduce it internally.

After a lot of back abd forth I asked if the user machine was wired. Nope, wireless laptop. Got them to plug in like their colleagues and it was fast again.
