the regression still exists on b2cf7507e186 and current tip of the branch:

you need build 7ee9887703 and its parent kernel with config in
https://download.01.org/0day-ci/archive/20240301/202403011511.24defbbd-oliver.sang@intel.com
then boot into kernel.
after that, you could run netperf in each kernel by following
https://download.01.org/0day-ci/archive/20240301/202403011511.24defbbd-oliver.sang@intel.com/reproduce
to get data.
the results will store in different path according the kernel commit, then you
could compare the results from both kernels.
what's your OS BTW? we cannot support all distributions so far...

we run performance tests on bare mental. for netperf, we just test on one
machine so the test is really upon local net.
