      Benchmarks showing that VDOM is somehow magically faster than DOM are nearly always suspect; case in point: https://github.com/marko-js/marko-vdom/pull/5 …https://twitter.com/slightlylate/status/901603718843457536 …

      Ok, patched. Either DOM or innerHTML is faster than Marko in all of these tests.

      BTW, I'm not bagging on VDOM or those who like it; I'm just asking for everyone to be honest their motives and the costs we impose for them.

      All of computing is built on going slower than hardware to let the humans catch up; it's often how we define "progress". C'est la vie.

      The question for us as engineers, however, is _can we afford those costs_ in a specific scenario? If not, it's *bad engineering* to pay them

      How many resources do you want to put in determining what is appropriate? Answer might depend on if you are methodological or opportunistic.

      A good baseline for today's web is "can I get TTI below 5s on http://webpagtest.org/easy  ?"

          That's a hard test: probably < 150k of critical resources (on the wire), exec on slow CPUs

          And even that is luxurious compared to what many users will experience over flaky networks and *really* cheap devices.

          Today on iOS it's easy: Safari renders the message their server is down locally.
