Parallel rendering matters because it increases page load speed. Let's say you have a page with 10 components that take an average of 100 ms to serve (including calls to db/soa, controller and view.) If loaded sequentially, your page will take 1 second. If loaded in parallel, it will only take 100ms (+ a little overhead.) You might think: "oh, but this is just rendering, but most of the time is in the models/db/soa". You'd be right in other frameworks. Lift is view-first, so it will figure out what components it needs to serve up based on the view and then parallelize all of the computation required to fulfill them.
