I Rewrote Our Python Data Pipeline in Rust: 3 Hours to 4 Minutes, 40x Faster
A real-world case study of rewriting a Python data pipeline with Rust + DuckDB. From 3-hour daily ETL jobs to 4-minute runs, memory usage dropped from 12GB to 600MB, and server costs cut by two-thirds.
Rust Compiler Pipeline Refactor: 35% Faster Build Times, But There's a Catch
Our team’s CI dropped from 42 minutes to 27 minutes just by upgrading the Rust compiler. This journey taught us one thing: performance optimization rewards those who measure, punishes those who guess.
Rust Lifetimes Scare Away 90% of Programmers? One Library Analogy Gets You There in Seconds
Compiler errors got you running? Relax. Rust lifetimes aren’t scary monsters—they’re invisible guardians ensuring your code never crashes. This 5-minute guide beats the official docs.
Rust Performance Pitfalls: When Rust Runs Slower Than Python
Rust performance optimization in practice: I watched my Rust rewrite get crushed by Python. The problem was data structure choice.
From 800ms to 90ms: How Rust Rayon Saved My Multithreading Nightmare
A real Rust concurrency case study: replacing manual threads with Rayon’s work-stealing scheduler and getting a 9x speedup.
io_uring Guide: Building High-Performance Servers with Rust and Async IO
A friendly deep-dive into Linux io_uring async IO technology, learn how to build high-performance servers with Rust and escape syscall bottlenecks
Rust mmap Memory-Mapped I/O: Why Reading Files Can Be as Fast as Accessing Memory
A plain-English guide to Rust mmap memory-mapped I/O. Why is it 5-10x faster than traditional Rust file reading? How does zero-copy achieve Rust performance optimization? This memmap2 hands-on tutorial uses real-life analogies to help you understand this seemingly mysterious low-level technology.
Rust 1.90 Upgrade Crash Report: My Codebase Didn't Make It
Performance tanked after upgrading to Rust 1.90? Here’s why and how to claw it back.
