-Performance
-===========
-
-Overview
-^^^^^^^^
-
-One of the benefits of FD.io VPP is high performance on relatively low-power computing, this performance is based on the following features:
-
-* A high-performance user-space network stack designed for commodity hardware:
-
- - L2, L3 and L4 features and encapsulations.
-
-* Optimized packet interfaces supporting a multitude of use cases:
-
- - An integrated vhost-user backend for high speed VM-to-VM connectivity
- - An integrated memif container backend for high speed Container-to-Container connectivity
- - An integrated vhost based interface to punt packets to the Linux Kernel
-
-* The same optimized code-paths run execute on the host, and inside VMs and Linux containers
-* Leverages best-of-breed open source driver technology: `DPDK <https://www.dpdk.org/>`_
-* Tested at scale; linear core scaling, tested with millions of flows and mac addresses
-
-These features have been designed to take full advantage of common micro-processor optimization techniques, such as:
-
-* Reducing cache and TLS misses by processing packets in vectors
-* Realizing `IPC <https://en.wikipedia.org/wiki/Instructions_per_cycle>`_ gains with vector instructions such as: SSE, AVX and NEON
-* Eliminating mode switching, context switches and blocking, to always be doing useful work
-* Cache-lined aligned buffers for cache and memory efficiency
-
-
-Packet Throughput Graphs
-^^^^^^^^^^^^^^^^^^^^^^^^
-
-These are some of the packet throughput graphs for FD.io VPP 18.04 from the CSIT `18.04 benchmarking report <https://docs.fd.io/csit/rls1804/report/>`_:

-Trending Throughput Graphs
-^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-These are some of the trending packet throughput graphs from the CSIT `trending dashboard <https://docs.fd.io/csit/master/trending/introduction/index.html>`_. **Please note that**, performance in the trending graphs will change on a nightly basis in line with the software development cycle:

-.. _developer-friendly:

-==================
-Developer Friendly
-==================
-
-This section describes the different ways VPP is friendly to developers:
-
-* Extensive runtime counters; throughput, `intructions per cycle <https://en.wikipedia.org/wiki/Instructions_per_cycle>`_, errors, events etc.
-* Integrated pipeline tracing facilities
-* Multi-language API bindings
-* Integrated command line for debugging
-* Fault-tolerant and upgradable
-
- * Runs as a standard user-space process for fault tolerance, software crashes seldom require more than a process restart.
- * Improved fault-tolerance and upgradability when compared to running similar packet processing in the kernel, software updates never require system reboots.
- * Development experience is easier compared to similar kernel code
- * Hardware isolation and protection (`iommu <https://en.wikipedia.org/wiki/Input%E2%80%93output_memory_management_unit>`_)
-
-* Built for security
-
- * Extensive white-box testing
- * Image segment base address randomization

-The FD.io VPP packet processing pipeline is decomposed into a ‘packet processing
-graph’. This modular approach means that anyone can ‘plugin’ new graph
-nodes. This makes VPP easily extensible and means that plugins can be
-customized for specific purposes. VPP is also configurable through it's
-Low-Level API.

- Extensible and modular graph node architecture.
-
-At runtime, the FD.io VPP platform assembles a vector of packets from RX rings,
-typically up to 256 packets in a single vector. The packet processing graph is
-then applied, node by node (including plugins) to the entire packet vector. The
-received packets typically traverse the packet processing graph nodes in the
-vector, when the network processing represented by each graph node is applied to
-each packet in turn. Graph nodes are small and modular, and loosely
-coupled. This makes it easy to introduce new graph nodes and rewire existing
-graph nodes.
-
-Plugins are `shared libraries <https://en.wikipedia.org/wiki/Library_(computing)>`_
-and are loaded at runtime by VPP. VPP find plugins by searching the plugin path
-for libraries, and then dynamically loads each one in turn on startup.
-A plugin can introduce new graph nodes or rearrange the packet processing graph.
-You can build a plugin completely independently of the FD.io VPP source tree,
-which means you can treat it as an independent component.

-This section describes the ways that VPP is fast, scalable and deterministic:
-
-* `Continuous integration and system testing (CSIT) <https://wiki.fd.io/view/CSIT#Start_Here>`_
-
- * Including continuous & extensive, latency and throughput testing
-
-* Layer 2 Cross Connect (L2XC), typically achieve 15+ Mpps per core.
-* Tested to achieve **zero** packet drops and ~15µs latency.
-* Performance scales linearly with core/thread count
-* Supporting millions of concurrent lookup tables entries
-
-Please see :ref:`performance` for more information.

-
-FD.io's Vector Packet Processing (VPP) technology is a :ref:`fast`,
-:ref:`packet-processing` stack that runs on commodity CPUs. It provides
-out-of-the-box production quality switch/router functionality and much, much
-more. FD.io VPP is at the same time, an :ref:`extensible` and
-:ref:`developer-friendly` framework, capable of boot-strapping the development
-of packet-processing applications. The benefits of FD.io VPP are its high
-performance, proven technology, its modularity and flexibility, integrations and
-rich feature set.
-
-FD.io VPP is vector packet processing software, to learn more about what that
-means, see the :ref:`what-is-vector-packet-processing` section.

-
-=================================
-What is vector packet processing?
-=================================
-
-FD.io VPP is developed using vector packet processing concepts, as opposed to
-scalar packet processing, these concepts are explained in the following sections.
-
-Vector packet processing is a common approach among high performance `Userspace
-<https://en.wikipedia.org/wiki/User_space>`_ packet processing applications such
-as developed with FD.io VPP and `DPDK
-<https://en.wikipedia.org/wiki/Data_Plane_Development_Kit>`_. The scalar based
-approach tends to be favoured by Operating System `Kernel
-<https://en.wikipedia.org/wiki/Kernel_(operating_system)>`_ Network Stacks and
-Userspace stacks that don't have strict performance requirements.
-
-**Scalar Packet Processing**
-
-A scalar packet processing network stack typically processes one packet at a
-time: an interrupt handling function takes a single packet from a Network
-Interface, and processes it through a set of functions: fooA calls fooB calls
-fooC and so on.
-
-.. code-block:: none
-
- +---> fooA(packet1) +---> fooB(packet1) +---> fooC(packet1)
- +---> fooA(packet2) +---> fooB(packet2) +---> fooC(packet2)
- ...
- +---> fooA(packet3) +---> fooB(packet3) +---> fooC(packet3)
-
-
-Scalar packet processing is simple, but inefficient in these ways:
-
-* When the code path length exceeds the size of the Microprocessor's instruction
- cache (I-cache), `thrashing
- <https://en.wikipedia.org/wiki/Thrashing_(computer_science)>`_ occurs as the
- Microprocessor is continually loading new instructions. In this model, each
- packet incurs an identical set of I-cache misses.
-* The associated deep call stack will also add load-store-unit pressure as
- stack-locals fall out of the Microprocessor's Layer 1 Data Cache (D-cache).
-
-**Vector Packet Processing**
-
-In contrast, a vector packet processing network stack processes multiple packets
-at a time, called 'vectors of packets' or simply a 'vector'. An interrupt
-handling function takes the vector of packets from a Network Interface, and
-processes the vector through a set of functions: fooA calls fooB calls fooC and
-so on.
-
-.. code-block:: none
-
- +---> fooA([packet1, +---> fooB([packet1, +---> fooC([packet1, +--->
- packet2, packet2, packet2,
- ... ... ...
- packet256]) packet256]) packet256])
-
-This approach fixes:
-
-* The I-cache thrashing problem described above, by amortizing the cost of
- I-cache loads across multiple packets.
-
-* The inefficiencies associated with the deep call stack by receiving vectors
- of up to 256 packets at a time from the Network Interface, and processes them
- using a directed graph of node. The graph scheduler invokes one node dispatch
- function at a time, restricting stack depth to a few stack frames.
-
-The further optimizations that this approaches enables are pipelining and
-prefetching to minimize read latency on table data and parallelize packet loads
-needed to process packets.
