    Phoronix: Benchmarking The Current Spectre + Meltdown Performance Overhead For 10 GbE Networking

    While running the Windows vs. BSD vs. Linux 10GbE network benchmarks among other recent 10GbE Linux network performance figures, the test request came in from a premium patron to look at the current 10GbE network performance hit as a result of the default Spectre+Meltdown mitigations...

    Hi,

    it could be great to test pps too (with 64bytes packet size for example) and not only bandwith... (BTW, what is the packet size in your tests ?)

      Why would you run intel_powersave as the scaler for server throughput tests?
      Also, I second the interrupt and context switch loading with small packet sizes spirit.
      BW is secondary to context changes in loading the CPU.

        That's the default P-State governor on most Linux distributions.

          I think some measure of CPU utilization would be interesting. I would expect a bigger difference, there.
