Tokio vs Thread Pools: How Async/Await Saved a Real-Time Platform from Performance Collapse

This case study demonstrates why architectural choices matter critically at scale—switching from naive thread spawning to Tokio's async/await reduced latency by 10x (500ms to 50ms) and slashed memory overhead by half. For developers building high-concurrency systems in Rust, embracing async patterns isn't merely a performance tweak; it's often the make-or-break decision that determines whether your platform survives launch day.
