Virtual Networking: Poll-mode vs Interrupt
Virtual Networking: Poll-mode vs Interrupt
The VMkernel is relying on the physical device, the pNIC in this case, to generate interrupts to process network I/O. This traditional style of I/O processing incurs additional delays on the entire data path from the pNIC all the way up to within guest OS. Processing I/Os using interrupt based mechanisms allows for CPU saving The post Virtual Networking: Poll-mode vs Interrupt appeared first on NielsHagoort.com .
