## How fast is Rust?
As always, this question is difficult to answer. There's still a lot of work to
do on speed, and depending on what you're benchmarking, Rust has variable
performance.
That said, it is an explicit goal of Rust to be as fast as C++ for most things.
Language decisions are made with performance in mind, and we want Rust to be as
fast as possible. Given that Rust is built on top of LLVM, any performance
improvements in it also help us be faster.
