    Not really sure where you get the idea that Ubuntu's default kernel has been optimized for servers. The kernel configs in Ubuntu are aimed as a multi-role config. It's not optimized specifically for server or desktop use. If you want a "in the can" default desktop kernel take a look at openSUSE where it defaults to a kernel that is "desktop tuned".

      There were slowdowns in Ext4 due to some changes, but this is about scheduler latency. Btw. Phoronix become so unresponsive it's hard to edit a post in time.

          The fact is that Linux is at the end of the feeding chain, so don't expect any big FPS in games, that's Windows world. This days will found some morons that will install Ubuntu on 700$+ system that's stupid. Linux can be very good for workstation and cheap one, that's it.

            Ya, don't know what is up with the server. But going back the scheduler improvements found in Win 7

            as well as other improvements

            These were not present in Vista.

            Of course there are many other factors which effect the end users experience as to what is responsive to them and what is not, such as pulseaudio (or really audio as a whole in linux), power management, graphics, etc etc. Yes I'm aware that most of the regressions come from the Ext4 filesystem but that has to be taken into account when talking about the end user experience.

              Good to see they're improving, but we don't know how well this improved latencies. While Linux kernel is probably more responsive (there's also RT Linux), more important for desktops are visible latencies which are sometimes caused by slow 2D.

              Yes, sometimes there are problems with this, but it depends on configurations.

              It depends if end users suffer from Ext4 changes, but they/we probably do.

              Linux is also very good for desktops. What's wrong with those FPS numbers (sometimes better then in Windows)? Games are very important for desktops, but there are also other things. Some people even prefer playing under Wine then keeping Windows on a hard drive.

                Indeed. If Wine solved their problem with DirectInput that makes more than 360 degree turns in UE-based games impossible, I'd make Linux my first OS. Unfortunately, they are still having trouble with latest XInput versions...

                  For some reason, some people seem to interpret the results as if Windows has won this benchmark big time. Is this because the title and the intro suggest that Windows might win, and the readers don't bother to read further?

                    This is for sure the case

                      Nice work, Michael!

                      The most important results are without doubt those of XPlane, Unigine and SPECviewperf, and Linux makes a strong showing in all. Specific anomalies aside, performance results are very similar to what I am observing in my own (non-PTS) tests.

                      We can safely ignore any test that exceeds 200fps or so. Performance differences above that point are meaningless and reveal little about real-world performance in modern software (they are equivalent to glxgears in that regard).

                      Finally, please don't feed the Ubuntu-is-not-Linux trolls.
