Hi Nathan,

I'm having a hard time reconciling two claims: (a) Node actually performs
less well than synchronous programming technologies, and (b) businesses
that do high volumes of web transactions say Node allowed them to process
more transactions more quickly while reducing the number of servers they
needed. These two things are causing a lot of cognitive dissonance in me.

I understand where you're coming from. You've heard big picture claims
about Node's efficiency and performance. I don't doubt the truth of them.

Then I offer a micro perspective picture into Node's architecture that
deals only with the performance impact of Node's event loop on Javascript
functions that implement async-await keywords. And that picture is
supported by benchmarks too.

What can we learn from both perspectives? I would suggest that Node.js is
really efficient at certain things, but can become really bogged down by
others. That it behooves application architects and engineers to know what
(and what not) to use Node.js for.
