Performance

Web Streams API locked you out? BYOB mode giving you headaches? Node.js core contributor James Snell proposed an alternative using async iterables, with 2x to 120x performance gains. See how pull vs push models affect your code performance.

PgDog is a Rust-based PostgreSQL proxy. They discovered Protobuf serialization was the real bottleneck in SQL query parsing — not the Postgres parser itself. By replacing Protobuf with direct C-to-Rust FFI bindings, they achieved 5-10x faster parsing.

When packet rates surpass 2 million per second, the Linux network stack simply gives up. It’s like your doorbell won’t stop ringing, but you never have time to open the door. Let’s talk about bypassing the kernel.

It compiles. It runs. It even passes stress tests… until production catches fire. Let’s talk about that classic async Rust pitfall everyone hits.

gRPC can indeed be much faster than REST, but most teams are right to stick with REST. Let’s talk about the real cost behind the speed.

Discovered that 13KB Axios is just a fetch wrapper. Using 25 lines of vanilla JS to achieve the same functionality while reducing bundle size by 92%. A real frontend performance optimization case.

Python 3.15 introduces a native JIT compiler that delivers 20% performance improvements without changing a single line of code. Here’s how to enable this experimental feature.

Performance tanked after upgrading to Rust 1.90? Here’s why and how to claw it back.

Rewriting AI Agent framework in Go brings 16x performance boost, 180ns agent startup, and only 1.2KB memory footprint - this is the extreme experience Agno-Go delivers
