    Phoronix: Linus Torvalds Lands A 2.6% Performance Improvement With Minor Linux Kernel Patch

    Linus Torvalds merged a patch on Wednesday that he authored that with reworking a few lines of code is able to score a 2.6% improvement within Intel's well-exercise "will it scale" per-thread-ops benchmark test case...

    So nice that it has been done by Linus himself and it will be part of the 6.12 release!
    That alleviates a bit the sadness of not having NTSync and up to date Zstd code too!

    Good job Linus and many thanks for everything you have done from us!

      Yeah, 'thanks' for being corporate bitch with 12 years old mentality.

        I'm thankful that in this universe being a corporate bitch with 12 years old mentality is not mutually exclusive with such corporate bitch improving the kernel's performance and its users being grateful for it.

          Don't worry everyone, the next Electron update will use 2.6% more CPU

          Didn't think you'd be allowed to have this did you?

            The only reasonable post I read in this entire thread.

              Was looking for someone that would spin this 2.6% optimization as a negative, not disappointed.

                If Linux can gain 2.6 percent with 10 lines, I wonder how many few lines tweaks = 2 percent optimization are hiding in the kernel leading to a potential x2 performance a few hundred LoC away… :P

                  There's a reason this is news: because such wins are rare, and especially when they involve such a minor code change.

                  Lots of people spend a lot of time analyzing kernel performance. For general-purpose stuff, I think there aren't huge gains lurking anywhere. You have to get into some of the corner cases, before you might find potential for big improvements.

                    If i'm reading this right, this doesn't really help you if you run with "mitigations=off" right?
