If you’re interested in the characteristics of how Phoenix achieves some of it’s performance, you definitely should take a look at this article, which talks about how Elixir - and by extension Phoenix - uses IO lists to significantly reduce template rendering times and memory usage.

Yep - this is spot-on. Even though it isn’t as fast in raw number-crunching as go/rust etc, it is unique in the way it maximises the work not done compared with most other web frameworks. This results in response times often measured in microseconds rather than milliseconds.

Sure, please do, thanks.
