 Posted: Mon Nov 01, 2004 2:54 pm Post subject: Slow GUI Performance as Compared to Windows |
 |
|
I am having a problem that is keeping me from using Linux. When I am in Linux and windows draw, for example, I can literally see the widgets like the buttons, window bar, icons, and text appear one by one in split second increments. Also, the move and resize window operations are terribly slow, too.
In Windows, everything is drawn "instantly" on the screen and is a lot snappier.
I have heard many people say that their desktop is just as fast as XP's. How can I achieve this performance in Linux? |

Which linux distro did you try?
and did you use xorg or xfree as the x server?
Doing things like compiling your own kernel will also help the graphics speeds.
My machine at home now runs much faster for both drawing and loading general applications than windows ever did, things like blender, the GIMP etc are wicked fast  |

Well, if you have either nvidia or ati I would recommend setting up the binary drivers from them ( both are in portage), when I use them the graphics are whicked fast on my box at home with gf4t4200, although sure the 2d performance is somewhat good using the normal driver it's much better with the drivers from nvidia/ati, befare though that I have had some problems with ati's fxglr driver, it crashes when I use xscreensaver on my laptop(ati4200) but it gives me a solid 1500 fps in a normal size window with glxgears (box at home gives me ~4000).
I have only used ati / nvidia with linux so this advice assumes you have one if not, then you have to find the driver to suit you.
So what graphics driver is your x using?

Definitely sounds like this user does not have DRI or DRM properly installed. This is still a sore spot for linux in terms of configuration because every card has different limitations and driver installation procedures.
What video card are you using and what does the command `glxinfo` produce when you run it from a terminal within X?
There is also a change you are using the wrong driver from within X. Vesa works but is very slow on some cards.
On some older cards, like my notebook running the vesa driver or even the correct (savage) driver without DRI makes the WM very sluggish. |

Why should glxinfo make a interesting output on this issue? Its GL and not 2D GUI drawing.
Interesting should be something like:
I use this graphiccard with these drivers on Xorg or Xfree on this machine with these specs with this WM/DE, including the versions of them. Tell us more about your setting, then we can help a lot more. |

glxinfo will tell you if DRI is actually usable, even if Xorg thinks it is it may not be. This is a common problem with lesser known or older video cards. |

That sounds logical. I thougt it prints only info regarding GL. Sorry, my fault. |

What are the specs on your machine?

what do you get when you run glxgears ?
I have similar specs and X runs extremely smooth on my machine, much faster than windows.

People don't have X faster than Windows when it comes to drawing operations. That's just plain impossible considering X's ancient concept of hardware "accelleration" (which is a lot slower than pure software for most operations today...). Some applications might "feel" faster, but X itself is definetly not.
As for widget redraw, using the xdamage extension you could reduce redraw times and flickering. Unfortunatly windows which are minimized or currently on another desktop are removed from the buffer (at least when using metacity...), so redrawing them is still as slow as always.
So, if you resize a window and scrollbars don't stay attached to the windowborder but lag slightly behind it, if moving one window over another (i.e. Mozilla ) causes the one below to flicker and redraw stuff, if changing tabs in gtk is dogslow when using pixmap themes or pixmap themes in general are about 40-60 times slower than they should be by any means, then everything is perfectly fine. Welcome to the world of xwindows.
On the brighter side, a lot of work is done by the xorg and fdo people. Maybe we'll eventually get desktop performance comparable to windows. Right now, that's just not the case though.
Now I know some people can't resist and will flame me. Before you do, you might want to google for "xrender vs imlib" or similar topics related to xwindows performance. Those benchmarks usually mean a lot more than just "it feels faster". I'm also not saying 'everything is bad', but I don't think claiming something is good when it actually is not is a good idea in the long run either.
