    Phoronix: Liquorix 3.8 Kernel Has Some Performance Wins Over Linux

    The Liquorix kernel is a modified version of the Linux kernel with out-of-tree patches and a kernel configuration that is highly-optimized for desktop, multimedia, and gaming workloads. It's been one year since last benchmarking the Liquorix kernel against a vanilla Linux kernel, but now we have some benchmarks of the Liquorix 3.8 kernel compared to the latest stable Linux kernel.

    So, they've just changed I/O scheduler from deadline to CFQ? Ubuntu's using deadline.

      That's BFQ, not CFQ.

        yep, BFQ (http://groups.google.com/group/bfq-iosched)... CONFIG_DEFAULT_BFQ=y

        there's also BFS in the config but apparently it's not enabled

          the difference between 3.8.0 and 3.8.6 is much bigger than i expected.

            so what were the differences in the kernel-config between stock Ubuntu kernel and Liquorix kernel config ?

              configs here... http://liquorix.net/sources/3.8/

              i never used liquorix, but if it shares code from zen-kernel (same author) then it also uses extra code/patches

                This is just crap compiled by a moron teenaged idiot underaged alcoholic. Completely not worthy of being reported on.

                And impossible to take seriously, anything that has been... inappropriately renamed (since its not even a fork of Linux, it *IS* the linux kernel)... in tribute to alcohol -- WTF is wrong with him?
                Whats wrong with offering DEB-packaged Desktop-optimized kernel for Debian Testing/Sid?
                I have been using it recently due to bug in original Debian kernel, which was fixed in 3.8, but Debian is still on 3.2, and the ride is pure awesomeness.
                For example, it can hibernate properly, unlike Debian.

                Liquorix rocks!

                But Michael made misguiding title for purpose - Liquirix IS a Linux kernel, Debian-packaged, Zenwalk-inspired.

                  The title was just easier/shorter writing over Liquorix 3.8 Kernel Has Some Performance Wins Over Vanilla/Mainline Linux Kernel.

                    Or more like "optimized"? : ) My reply wasn´t meant as offensive at any degree anyway, this project is very worth mentioning!

                      You could also use 3.8 from experimental.

                        If you use Kanotix you can even use kernel 3.9 with wheezy

                          If it is supposed to be measuring desktop performance...

                          ...then it should use benchmarks that measure latency. For example, try copying a 4 gigabyte file and start firefox at the same time, and measure how long it needs before firefox is fully usable.

                            What About Latency?

                            What about measuring things that matter for a desktop and gaming machine such as worst frame performance and input-to-response latency, especially worst-case latency?

                            There's not much that is more annoying than typing in a text editor or word processor and having everything freeze solid for two seconds because a large disk job started running in the background.

                              Liquorix is rather stable, desktop-optimized and easy to install. So, no, I couldn't.
