So I ran the "reproduce" script in the original mail on a KBL box here
with the .config tailored for it:

cpu family : 6
model : 158
model name : Intel(R) Core(TM) i5-9600K CPU @ 3.70GHz
stepping : 12
microcode : 0xd6

and I get mixed results. But I'd need to know how exactly they generate
the metrics "netperf.Throughput_total_tps" and "netperf.Throughput_tps"

Feng?
