+Impact of SpectreAndMeltdown Patches
+====================================
+
+Following sections list changes to VPP throughput performance after
+applying patches addressing security vulnerabilities referred to as:
+Meltdown (Variant3: Rogue Data Cache Load) and Spectre (Variant1: Bounds
+Check Bypass; Variant2: Branch Target Injection) security
+vulnerabilities. Incremental kernel patches for Ubuntu 16.04 LTS as
+documented on
+`Ubuntu SpectreAndMeltdown page <https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown>`_.
+For Spectre additional Processor microcode and BIOS firmware changes are
+applied. Detailed listing of used software versions and patches is
+documented in :ref:`test_environment`.
+
+NDR and PDR packet throughput results are compared for 1-core/1-thread,
+2-cores/2-threads and 4-cores/4-threads VPP configurations, with
+reference performance numbers coming from tests without the Meltdown
+patches. Tables show test results grouped into Best 20 changes (minimal
+performance impact), followed by Worst 20 changes (maximal performance
+impact). All results are also provided in downloadable CSV and pretty
+ASCII formats.
