asynchronous - Building async web apps with playframework -


actually question not targeting play framework, general question async programming.

i know in play, can use:

ws.url(url).get()

to make rest call async return promise/future. (i guess might supported underlying nio library netty or spray.io)

so, question is: build async web application, every i/o bound operation has better async, right? otherwise, bottle neck?

let's have simple web application calls jdbc , return query value browser.

in case, suppose don't have async/reactive jdbc driver, play2 performs better servlet solution?
