Hi All,

Trying to follow the specific conversation.  It is correct, the lab does
not list the specific throughput values achieved by the hardware, as that
data can be sensitive to the hardware vendors, etc. The purpose of the lab
is to check for degradations caused by patches, so the difference is really
the important factor.  The comparison is against a prior run on the same
hardware, via the DPDK main branch, so any delta should be caused by the
specific patch changes (excluding statistical "wiggle").

If the group would prefer, we could calculate additional references if
desired (i.e. difference from the last official release, or a monthly run
of the current, etc.).  We just need the community to define their needs,
and we can add this to the development queue.

Cheers,
Lincoln
