Each time NIC receives incoming packets, there is a kernel interrupt to process the packets and a context switch from kernel space to user space. This creates delay. With the DPDK, there is no need for interrupts, as the processing happens in user space using Poll mode drivers. These poll mode drivers can poll data directly from NIC, thus provide fast switching by completely bypassing kernel space. This improves the throughput rate of data. 0 1 2 3 4 5 6 7 8 Without DPDK With DPDK Performance can increase by 4-5x
