OS does not serve requests -- applications do. While it may be possible to demo a toy OS+app, real-world applications take seconds if not minutes to start and warm up. Throughput on a cold-cache is a fraction of that on a warm cache. Starting in milli-seconds is not the hard problem. Starting + warming caches in that time is -- that will get you a bunch of awards when you solve it.
