Abstract
Cache hits are increased for URBs that target a redirected USB device. When a virtual bus driver in a VDI environment queues an IRP for an URB that targets the redirected USB device, it can ensure that the IRP and therefore the URB is completed on the same processor that originated the URB. This can be accomplished in both NUMA and non-NUMA multiprocessor environments.
