Current vs Previous Release
---------------------------

Relative comparison of DPDK Testpmd and L3fwd packet throughput (NDR,
PDR and MRR) between |dpdk-release| and |dpdk-release-1| (measured for
|csit-release| and |csit-release-1| respectively) is calculated from
results of tests running on 3n-icx, 2n-ics, 2n-clx, 2n-zn2, 3n-tsh, 2n-tx2
testbeds in 1-core and 2-core configurations.

Listed mean and standard deviation values are computed based on a series
of the same tests executed against respective DPDK releases to verify
test results repeatability, with percentage change calculated for mean
values.

.. note::

    Test results are stored in
    `build logs from FD.io dpdk performance job 3n-icx`_,
    `build logs from FD.io dpdk performance job 2n-icx`_,
