Efficient I/O request handling

Abstract:

A method of efficient message transmission includes a hypervisor receiving a first input/output (I/O) request from a ring buffer; receiving a second I/O request from the ring buffer; receiving an absence of further I/O requests from the ring buffer; comparing an aggregate size of a first message and the second I/O request to a maximum transmission unit, wherein the first message comprises the first I/O request and a first protocol overhead; generating a combined message, in response to the aggregate size of the first message and the second I/O request being less than the maximum transmission unit. The combined message comprises the first I/O request, the second I/O request, and the first protocol overhead; and forwarding the combined message to an I/O target.
