    Ubuntu Debian, kinda the same thing. Anyway looks like MOST these advantages could easily be turned on in any of these distros, for example I always turn on DRI3 now, its one of the first things I do. Would be nice to know what compiler flags are being used with clear and if their safe to toggle on in other distros....

      Thanks for those details, if performance is due to optimization then... good job

      (I used to play too much with flags before and had a lot of surprise so I was puzzled about how you did achieve this)

          Seems to be a little bit more than just compiler optimizations. Check out all the patches in glibc alone!!
