    Phoronix: Linux 4.14 vs. 4.20 Performance Benchmarks - The Kernel Speed Difference For 2018

    As some additional end-of-year kernel benchmarking, here is a look at the Linux 4.14 versus 4.20 kernel benchmarks on the same system for seeing how the kernel performance changed over the course of 2018. Additionally, Linux 4.20 was also tested a second time when disabling the Spectre/Meltdown mitigations that added some performance overhead to the kernel this year...

    Yaaay, Linux is getting slower!

      It would be interesting to see how that comparison measures up when using Ryzen/EPYC.

            AMD tests are coming in the days ahead.

              Michael How about 4.14.0 vs 4.14.89 to test the effect of the security mitigation patches?
              Thank you.

                An interesting comparison would be to repeat the test on an otherwise well supported platform unaffected by the various speculative execution bugs, such as a Pi 3. For x86, 2019 is likely to see a major effort trying to mitigate the mitigations and bring performance back up near 2017 levels.

                  It would also be interesting to see how an older intel CPU like an i7-2600 or i7-3770 regressed ...

                    Hopefully AMD results will be more promising.
