Tried this on a Power9 platform (3.6GHz), with two numa nodes and 16
cores/node (SMT=4). Applied all 3 patches in v5, test results are as
follows:

Thanks for running this. There is another test 'ring_perf_autotest' which
provides the numbers with the original implementation. The goal is to make sure
the numbers with the original implementation are the same as these. Can you
please run that as well?
