- 01:06, 21 November 2025 PC talk contribs created page Why Discord Migrated Read States from Go to Rust (Created page with "500px The pattern was unmistakable: every two minutes, like clockwork, Discord’s Read States service would spike to 10–40 milliseconds of latency. Users would experience tiny but noticeable delays when loading channels or seeing new messages. For a platform built on feeling “super snappy,” this was unacceptable. The Read States service handles one of Discord’s most critical functions: tracking which channels and messages users...")

Written with Tokio, leveraging async/await, serving static assets at 45,000 requests per second on modest hardware. The code was clean, the architecture was sound, and the CPU usage sat at a reasonable 60%. We’d reached what felt like the natural limit of network I/O performance. Then we profiled with perf and discovered something startling: 42% of our CPU time was spent in the kernel, no...")

Authentication, logging, graceful shutdown, metrics — all the boring stuff that isn’t in tutorials but breaks in production at 3 AM. And every time I thought “I should just make a proper template” but then I’d get lazy or distracted or convinced myself this time would be different. Spoiler: it wasn’t different. It was the same problems, same debugging sessio...")

In high-performance systems, p99 latency is where the real pain lives. Users rarely care about average response times — they care about the outliers, the tail latencies that make an app feel sluggish under load. Rust’s zero-cost abstractions promise safety without overhead, but the reality...")

This approach works until it doesn’t. When you’re ingesting thousands of GPS updates per second from trackers across multiple tenants, that direct-to-database approach becomes your bottleneck and your single point of failure. The symptoms are always the same: timeouts spike during traffic bursts, the database...")

(Created page with "Subtitle: A teardown of Rust’s mutex internals plus real benchmarks so you know when to choose std or parking_lot. A while ago, our team was working on a Rust project where std::sync::Mutex was everywhere. A team member suggested switching to parking_lot::Mutex instead. They heard that it has better performance, smaller memory footprint, and more predictable behavior under contention. I had no idea how to evaluate this claim. A quick search online returned results...")

Like magic. But behind that one-liner lies a dance between the Rust standard library, the system’s libc, the OS kernel, and your CPU’s scheduler — a dance so tightly choreographed that a single misstep could cost milliseconds… or deadlock your app. This article is the human story of that journey — how Rust spawns a thread, how the O...")
