I got below results on my environment, but confusing with the cycles
percents, it looks like the polling plus processing cycles per pmd is 100%,
but as I recalled there are some improvment document that showed their
processing cycles are 100% percents which means 0 for polling cycles? how
should be the rate of polling and processing cycles take? should it be
better for less polling and much processing for performance's benefits?
pmd thread numa_id 1 core_id 27:
avg. subtable lookups per hit:1.00
polling cycles:19832152639760 (12.60%)
processing cycles:137517517407771 (87.40%)
avg cycles per packet: 1113.33 (157349670047531/141332792711)
avg processing cycles per packet: 973.01 (137517517407771/141332792711)
Thanks a lot.
