Interrupt coalescing - Wikipedia

Interrupt coalescing, also known as interrupt moderation, is a technique in which events which would normally trigger a hardware interrupt are held back, either until a certain amount of work is pending, or a timeout timer triggers. Used correctly, this technique can reduce interrupt load by up to an order of magnitude, while only incurring relatively small latency penalties. Interrupt coalescing is typically combined with either a hardware FIFO or direct memory access, to allow f… shoes export tariff code

WebAug 10, 2015 · Timer coalescing is based on the idea of a “tolerable delay” for the timer expirations. Given some tolerable delay, the Windows kernel may adjust the actual expiration time to coincide with any existing timers. A good rule of thumb is to set the delay to one-tenth of the period in use. For example, if the timer should expire in 10 seconds ...
