           Summary: Fix performance test stability on Mellanox 25G and 40G
           Product: lab
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: Normal

  Target Milestone: ---

The 25G and 40G NIC tests are currently disabled from production testing, due
to test stability, where the 256 Byte packets some to drop in performance
during some test runs.  The following test runs have examples of this behavior.

 Patch Set  Failure 
 102941  Mellanox 40G 256 Byte -1.79% 
 102937  Mellanox 40G 256 Byte -2.8% 
 102927–102933  Mellanox 40G 64 Byte -5.5% 
 102903  Mellanox 40G 256 Byte -2.1% 
 102890  Mellanox 40G 64 Byte -1.7% 
 102886–102887  Mellanox 40G 64 Byte -2.0% AND Mellanox 25G 64 Byte -5.6% 
 102884  Mellanox 40G 256 Byte -1.79% 
 102879–102880   Mellanox 40G 256 Byte -2.0% 
 102857  Mellanox 40G 256 Byte -2.5% 
 102856  Mellanox 40G 256 Byte -2.4% 
 102835  Mellanox 40G 256 Byte -2.19% 
 102800–102801  Mellanox 40G 256 Byte -2.1%
