Rust webserver to replace Apache/WSGI

Hello, I need to scale an app made with Django and am reviewing Actix-web and Rocket.
In terms of load, can an application be built so that it can support 100M users and high traffic, with cryptographic features? Does someone have experience with that kind of project? Any opinions are welcome.

With best regards,

At least in synthetic benchmarks Actix-web is one of the fastest web frameworks, and much faster than Rocket and Django.

Scaling to a specific number of users depends on other factors like the network, hardware, and how you implement the cryptography part, but Actix-web should be a good choice for it and won't hold you back.
