    Low efficiency in Fedora 10

    I updated to Fedora 10 as soon as it was released. But it brought me headache when I edit my slides with OpenOffice.org Impress. Switching between text fields costs a long time, and playing the slides unbearably longer.

    Eclipse loading was another problem. It was more than 40 seconds from my click to the window showing up. The screen paused from time to time when I scrolled over the codes.

    I wonder if it was a RAM problem or video card one. My machine has 512MB of RAM and an ATI 7500 card. glxinfo shows I had Direct Rendering on. But the 2D game supertux runs like superslowtux. Could this be the driver's fault? How could I check it up?

    launch a terminal and use the "top" command, see if anything is munching your resources
    Linux is more then an Operating System, it's a state of mind, a way of life :eek:

    I saw nothing weird in the list. And resource seemed adequate. But running application...

    You are a bit low on ram for your usage, swap usage is >100mb. Are you running OpenOffice whilst other resource hogs like firefox and eclipse are open?

    No, not.
    I restarted the system to release the messed memory and tried to edit and view my slides with no other application running. And Impress said "no, I won't let you happy" (it didn't really say) and still played with a bad attitude.

    It's specially annoying the machine runs super slowly when you are in a hurry to catch up with project procedure. I need at least some encouragement to stick with Fedora 10. Maybe I need to switch to some other system to finish my work first? I regreted a lot deleting Fedora 9 from the disk yesterday. 9 was such a nice guy who never made me out of my mind. Now he's gone...

    Btw, the new system used more than 210MB under fresh boot...

    Keep an eye on which app is hogging the memory, there may be a memory leak in OpenOffice, 512Mb should be enough for the task.

    Open a terminal window, type 'top' and press Shift G then 3, now leave the window open and monitor the top app usage.

    Thank you sideways, it was too late yesterday and power was cut then so I can't access the internet to post back.

    Code:
      PID %MEM  VIRT SWAP  RES CODE DATA  SHR nFLT nDRT S  PR  NI %CPU COMMAND      
     2118  7.8 73804  32m  39m    4  52m 6416   63    0 S  20   0  0.0 setroubleshootd
    This is what's there.
    And I do have adequate free memory when the slowdown thing happens.

    Is it possible that the video card driver slows everything down? Because:
    (1) Raedon 7500 Mobility is quite old.
    (2) When I switch between opened windows, window decorator reacts slowly. Normally it leaves areas unfilled for seconds.

    Is there anyone running Fedora 10 on a 4-year-old machine? How's your situation?

    This sounds like a video driver issue. See if you can turn off DRI and compositing.

    BTW., >1 minute to start up eclipse is fairly normal for my 512MB PIII machine. Eclipse is a monster.

    I have Pentium M 1.5GHz and it loads fast in Fedora 9. Note that switching between windows of small applications causes delay as well.

    I'll try your suggestion. But how to turn DRI off?
    Thanks.

    Now, since I've closed your other thread on this subject I'll offer some suggestions. Is it possible for you to add system memory? 1GB will be exponentially better than 512MB although 512MB should be plenty. Also, if this is a desktop computer (you asked that the thread be moved to Genera Support) what are the chances of trying a different video card or installing the correct drivers for the existing card? How about posting all the pertinent system specifications? Make, model, drive, processor (you said Pentium M 1.5Ghz), video card (Radeon Mobility 7500), etc? Are you using wireless or wired internet or both?

    Add more memory. It's the runaway winner in the competition for the first thing you should look at.

    Whilst waiting for the extra memory to arrive, look at which services are running. Do you really need all of them? Don't know what you want from this machine, so I can't tell you which ones you can do without. NFS is not commonly used on a desktop for example.

    Cheers
