    I can read it. It is annoying to read, but not impossible. Still a bad color for text on a white backgroudn.

    because the systems are completely different? the i5 has a 240gb ssd whereas the i7 has a pair of 120's which would explain the IO tests. the i5 is also clocked 100hz higher than the i7, the i7 has 6 cores vs the i5's 4 cores. the differences go on and on.

    and as the intro said, they are not comparing the systems to each other - but against themselves for the kernels

    Didn't mean to seem like I was busting your walnuts. I understand the struggle. That's why I subscribed. BTW....when do I need to re-subscribe?

    Michael, I can read it, but if I were to change it I'd use matplotlib's new color tableau:
    https://github.com/matplotlib/matplo...or_data.py#L19
    and then cycle over linestyles/hatch-pattern when running out of colors.

    EDIT: impressive work as always!

Ubuntu is especially late on these patches. As these mitigations are still being worked on, "pure" kernel performance is hard to be seen. Performance may go up and down any moment.
    Initial Retpoline support for x86_64 landed last month, not at the start of February, albeit other Retpo/kpti improvements in 4.16.
