-Impact of Meltdown Patches
-==========================
-
-Following sections list changes to VPP throughput performance after applying
-patches addressing security vulnerabilities referred to as Meltdown
-(Variant3: Rogue Data Cache Load). Incremental kernel patches are
-applied for Ubuntu 16.04LTS as documented on
-`Ubuntu SpectreAndMeltdown page <https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown>`_.
-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.
