-Performance Impact of Meltdown and Spectre Patches
-==================================================
-
-The following tables present performance impact on VPP after applying
-patches addressing 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. For detailed listing of used software versions and patches
-please refer to :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 and
-Spectre patches.
