Ubuntu is slower than Windows

Closing this bug as it is too un-specific. Please try to diagnose the problem firther somewhere else in the community (Forums or IRC would be your best bet) and file a bug once you find the cause of the slow down.

Do you have visual effects enabled in ubuntu? If so, try to turn them off, you'll see most apps are starting a lot faster. If you want to compare speed of ubuntu with visual-effects turned on with windows, you should compare ubuntu with vista running aero, not with xp.

Another thing is, you're running a development-version of ubuntu, so not everything is working as expected yet. Is there something in the boot-up sequence that takes a lot longer than you believe it should? If so, can you please try to specify what is causing the delay, e.g. using bootchart?

In general I don't believe that you're able to compare windows with ubuntu or another linux-distro 1:1, because the philosophies and techniques of the two os-es are different (which is one of the reasons why I'm using ubuntu: I don't want to have a windows-clone).

I usually have visual effects enable, but I tried disabling them, so you don't have to wait for the animations.

Still is slightly slower than Windows.

Maybe you cant compare Windows to Linux 1:1, and maybe a Windows-clone is not a good idea, but I don't want worse performance than Windows.
I want either same performance, or better.

>I want either same performance, or better.

Right. But if you do not specify what is causing (or at least may cause) the delay, nobody will be able to look at this. A simple meta-bug "ubuntu is slower than windows" does not help anyone because it may depend on your specific setup.

On my dual-boot machine windows seems to be slower than ubuntu, but this does not mean it really is or that it is so because in general ubuntu is faster. Maybe it is just an issue of an app being loaded on startup causing delay (antivir-program or something like that). I don't care, because I'm not using windows anymore for daily tasks.

Again, you cannot simply compare startup time of app x on os 1 with app y on os 2, because there are a lot of things which may cause the differences, e.g. app x on os 1 is using already loaded and cached libraries while app y on os 2 will need a library not yet cached in memory, an effect app z with similar purpose will not show. There are a lot of other things which should be considered, before you can really compare something like this.

I don't have 'bootchart' or anything on Ubuntu.

GNOME loads much slower on Ubuntu than the Windows shell loads on Windows XP.

The GNOME Panel 2.21.91
It feels like GNOME Panel is loading slower too at startup.

Also about comparison, you can say that you cant compare, but most people don't care about cache, libraries and the inner workings. They just want it to be fast, and will use whatever operating system feels fastest to them, and Windows does feel faster to me.

Have you try other lighter window managers? I mean, for example, Xfce4 on Xubuntu?
If GNOME is the cause of slower loading, it may be a little faster, and maybe you like it.

Yes, I have tried Fluxbox. It starts much faster than GNOME.

But it is not so good for non-advanced users because its not good usability, not so efficient work or easy to use.
