Let's see how the maintainers would like to proceed. 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? -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
