Zig vs Rust Performance Benchmark 2026

In this video we’ll compare Rust and Zig — the fastest web frameworks that I could find for each language. We’ll measure latency, throughput, CPU, and memory usage. This is a very simple test: when the client sends a GET request, the server responds with a “Hello World” string. I ran it on AWS using large instances, and each framework uses 2 workers to utilize the entire VM. Let’s go ahead and run the test. Zig framework uses busy-loop by default — that’s why you’ll immediately see full 100% CPU utilization. Let me run the test for another minute. Well, you can see that Zig slightly outperformed Rust, but not by much. In terms of latency (which is better when lower), Rust performed better. Let me know what I should test next!
