WebWe also investigated the performance of two latency micro-benchmarks, one for InfiniBand devices and another for networking devices, in VM DirectPath I/O (passthrough) mode, which bypasses most of the virtualization stack except the path for delivering interrupts from the underlying physical devices to the guest OS. Applying the WebFigure 23: DPDK-accelerated OVS with DPDK enabled VNFs. To improve the performance of OVS with DPDK, vHost user multiqueue support was introduced. vHost user as explained earlier improved overall throughput by allowing the VM that runs in user space to bypass the QEMU and directly talk to the kernel memory using sockets.

"Webbuild the lowest latency request-response system that we can. Following the clean slate approach, we developed a very simple, and very fast, minimal object store evalua-tion application that supports only two operations: GET and SET. The minimal object store application exhibits low absolute latency, but it also has low latency vari-ability. " - Towards low latency interrupt mode dpdk
