- 4Hacker News·9/14/2026researchPrinciples for Fast Tokio Applications
This article outlines practical guidance for improving performance in async Rust applications built on Tokio, with an emphasis on measuring real bottlenecks before changing code. It discusses tradeoffs between latency and throughput, fairness, batching, mutex contention, parallelism, and runtime isolation, while noting that many performance problems originate in application logic rather than Tokio itself.
