Dart team posts an example of fast code with 22ms for a “Hello world”

The text on the page is "AOT-compile apps to native machine code for instant startup".

And now you're saying that the start up is actually not instant.

- LuaJIT: 0.002ms [1]

- Dash and perl take about 2ms. Python takes 12. [2]

- Perl 0.008s [3]

- Python 0.009s [4]

And that's before we talk about compilation speeds [5]

"Instant" is a relative word (unless we're actually at 0 time :-)).

We're focus on client apps, where we're really focused on human perception. In that sense, I'd consider 22ms or 2ms as instant (for startup). I wouldn't consider 2s as instant.

I'm not saying Dart doesn't have room to get better, but there are diminishing returns at a certain point.

22ms here. 22ms there. "Focused on human perception" here, "Focused on human perception" there.

And suddenly we have what is basically a supercomputer unable to perform anything without lag.
