Stop Slowing Down Your Rust Threads: Use Parking Lot | Rust Concurrency Trick
Learn how thread locking affects performance in Rust and why lock contention matters. We start with the common mutex from the standard library and observe how it behaves under load.
Then we explore the parking lot crate and see how it reduces waiting overhead. This helps keep threads active instead of sleeping and waking repeatedly. By the end you will know when to choose the standard mutex and when to switch to parking lot.
