You raise a question, but there's a missing detail in your input - how many machines (and what kind) you are using.

If you have 80,000,000 machines serving 80,000,000 requests - that's not very impressive. Even if you have 80 servers, that's extremely unimpressive.

If you can do all of that on 1 server, then YOU probably don't need async. In fact, unless you're wasting time, 80,000,000 averages less than 10 requests/second, and peak is likely less than 100 requests/second. That's really not much - I do that with interpreted python.

But every language does need facility for async processing.

edit: it's 1000/second, not 10/second, as everyone down here corrected. Apparently, I cannot math before coffee. (I don't drink coffee). Apologies.

fun mnemonic: the number of seconds in a day is 864e2. (eight-six-four-(e)-two).
