10:06 another important difference is the user time, which went from 0.01s to 2.00s (due to the busy loop ofc)
0:21 If I called my event loop an "executor" I'd probably give it egg-themed branding reminiscent of the Exeggutor Pokemon and make it emit their Gen 1 cry when ran.
For the Rust implementation, I would use the macro `join!` from the crate you've used, `futures`, it behaves similarly to the C++ variadic `gather`, you don't need to use a collection.
Great overview of async/await for many different languages! It takes so much more effort to provide a comprehensive story for multiple languages than just for one language so I really appreciate the effort you put in!
Hi, I have a simple qstn that bugs me often : is event-loop based concurrency is less performant than the thread/coroutine based concurrency?
