My guess is that "fastest" refers to the request-response loop.

I'd be interested in knowing how fast it is once you tack your favourite template rendering engine on top.

It would be nice if there were drop-in support for Tera, the Rust template engine that is inspired by Jinja2:

Here is a benchmark on TechEmpower - https://www.techempower.com/benchmarks/#section=test&runid=4...

I also have a comparison on the docs website: https://sansyrox.github.io/robyn/#/comparison

And my own benchmark code is https://github.com/sansyrox/robyn-comparison-benchmarks
