9 One of the benefits of FD.io VPP is high performance on relatively low-power computing, this performance is based on the following features:
11 * A high-performance user-space network stack designed for commodity hardware:
13 - L2, L3 and L4 features and encapsulations.
15 * Optimized packet interfaces supporting a multitude of use cases:
17 - An integrated vhost-user backend for high speed VM-to-VM connectivity
18 - An integrated memif container backend for high speed Container-to-Container connectivity
19 - An integrated vhost based interface to punt packets to the Linux Kernel
21 * The same optimized code-paths run execute on the host, and inside VMs and Linux containers
22 * Leverages best-of-breed open source driver technology: `DPDK <https://www.dpdk.org/>`_
23 * Tested at scale; linear core scaling, tested with millions of flows and mac addresses
25 These features have been designed to take full advantage of common micro-processor optimization techniques, such as:
27 * Reducing cache and TLS misses by processing packets in vectors
28 * Realizing `IPC <https://en.wikipedia.org/wiki/Instructions_per_cycle>`_ gains with vector instructions such as: SSE, AVX and NEON
29 * Eliminating mode switching, context switches and blocking, to always be doing useful work
30 * Cache-lined aliged buffers for cache and memory efficiency
