Rust Is Safe. But Is It Fast?

Rust promises developers the execution speed of non-managed languages like C++, with the safety guarantees of managed languages like Go. Its fast rise in popularity shows this promise has been largely upheld. However, the situation is a bit muddier for the newer asynchronous extensions. This talk explores some of the pitfalls that users may face while developing asynchronous Rust applications that have direct consequences in their ability to hit that sweet low p99. I share how the Glommio asynchronous executor tries to deal with some of those problems, and what the future holds.
