Adaptive Spinlock Backoff Strategy

Medium · concurrency · Quant Developer interview question · concurrency, low-latency, spinlock, c++

Efficient thread synchronization is crucial to minimize latency while preventing CPU starvation. An adaptive backoff strategy optimizes this balance by dynamically transitioning between busy-spinning, thread yielding, and sleeping based on the wait duration. This mechanism reduces expensive context switches for short waits while conserving resources during longer delays. Task Implement the wait method within the BackoffWaiter class to execute an adaptive backoff loop. The method accepts a condi
