Why Thread.Sleep(0) Can Change Your App’s Responsiveness – The Real Reason

Thread.Sleep pauses a thread for a specified time, but its behavior depends on OS scheduling; Sleep(0) yields the CPU to let other threads run, while Sleep(1000) doesn’t guarantee immediate wake‑up, illustrating how time‑slice and priority‑based scheduling affect thread execution.
