I feel like this becomes less clear if you're talking about "one-time" events. "Our website loads 2x faster now" doesn't mean that they are sending more data per second, and the user won't be doing more website loads. The website load time going from 1 second to 0.5 seconds is "2x faster" and I think that that is a very common way of communicating such performance increases too.
