1 Performance Impact of Meltdown Patches
2 ======================================
3
4 The following tables present performance impact on VPP after
5 applying patches addressing Meltdown (Variant3: Rogue Data Cache Load) security
6  ulnerabilities. Incremental kernel patches are applied for Ubuntu 16.04LTS as
7 documented on `Ubuntu SpectreAndMeltdown page <https://wiki.ubuntu.com/SecurityTeam/KnowledgeBase/SpectreAndMeltdown>`_.
8 For detailed listing of used software versions and patches please refer
9 to :ref:`test_environment`.
10
11 NDR and PDR packet throughput results are compared for 1-core/1-thread,
12 2-cores/2-threads and 4-cores/4-threads VPP configurations, with
13 reference performance numbers coming from tests without the Meltdown
14 patches.
