kubuntu is very slow

Re: kubuntu is very slow

I also note that you have ntfs-3g running. My personal experience of this is that I have known it to keep my hard drive banging away at times.

Presumably you are dual booting with Windows being the other OS, which is why ntfs-3g is installed? If so, do you need to actually access the windows partition from within 'buntu? Alternatively, is the USB hard drive formatted in ntfs? What happens if you run with it unplugged?

Re: kubuntu is very slow

when I check inder Kinfo in memory this is what I see. Also i did lower down my upload and my download, it did management to increase the computer speed but from no parent reason my cpu fan is going berserk for 30 min and than come down, it does that every 5min.

Re: kubuntu is very slow

Do you have a dual-boot, and if so does the other OS also have problems with speed?

Question to others: could this have to do with the wrong video driver, which makes the CPU busy with rescaling for the screen resolution?

Re: kubuntu is very slow

well I do have a dual boot but I want to take it off. Also I have a ATI all in wonder 9600 and the xorg as reconize well, my monitor is 17inch LCD Sony sdm-M81, but there is no driver for this. And for my NTFS-3g, this is my external HD 500g. if I unplug it nothing happen.

digichikmon, it was gratifying to see:

I'd suggest that you completely turn off all kind of torrent activity on your machine. That way you could be sure that this is not really eating up too much resources. If after quitting all torrent (or Donkey, or...) software, if your machine still feels slow I'd look at the graphics drivers as JohanLingen is suggesting.

First, disable desktop effects and see if it makes a visible difference. Does it?

Re: kubuntu is very slow

ok,
I shutdown the torrent apps, lower down the graphic effect, and still slow. I check on my ATI driver and is ok it doesn't said is a generic driver. I also found out that every time a start my computer it seem that my external HD doesn't kick in. mean that every time I have to go to the dolphin to activate it. Man! I wonder more and more if it was a good ideal to be in kbuntu instead of windows. I'm having a very hard time on this!

Neither does mine. But when I boot Windows, the external USB HD does not get mounted on start up, and I've never assumed that this was a problem with both, although I've missed that behavior in both Windows and Linux.

Suggest that you keep both, sometimes for work or fun there is no viable alternative than to run Windows.
Can you take your "top" screenshot again? After disabling graphics effects and closing torrents, you should have (according to your latest top screen) about 20% more CPU available, it's strange that you don't feel the system performing better.
Another possible source is that the apps take a lot to start but then the performance is not bad. Are you referring to that? If so, can you paste the contents of your /etc/hosts file?
