Abstract
A method for coalescing IO requests includes maintaining a queue in a layer of an IO stack of a hypervisor, wherein (i) the queue holds IO requests received from an upper layer of the IO stack without forwarding the IO requests down the IO stack, and (ii) the layer of the IO stack resides above a file system layer of the IO stack. The method further includes receiving, at the layer, an IO request from the upper layer or a notification of a completion of certain IO requests previously transmitted by the layer down the IO stack. The method further includes determining whether any IO requests currently held in the queue should be transmitted down the IO stack based upon a condition; and combining any IO requests in the queue into at least one combined IO request to transmit down the IO stack if the condition is satisfied.
