Posted: Fri Sep 14, 2012 1:39 pm Post subject: KDE 4 performance deteriorates over time. |
|
|
Hello,
I'm a long time GNOME user, but recently decided to give KDE 4 a shot - and generaly I am impressed and positivley suprised.
Currently I'm using KDE 4.9.1 (latest in ~x86).
After logging in everything works excelent, fast and resposive, but after some time (hr or so) drawing get slower and slower. Changing tabs in editors or web browser takes quite some time and You can notice how element being rendered one by one.
After relog everything gets back to normal for same amount of time. I've tried to disable effects completely but it has no effect.
CPU usage is OK, and I don't have any errors in my logs when this problem occurs.
Basic informations:
linux-3.5.3
nvidia-drivers-304.37
Oxygen style for QT and GTK.
Qt settings:
Compositing type: XRender
Qt graphics system: Native
eselect qtgraphicssystem: native
Any ideas? |

Take OpenGL for compositing type. |

I've noticed this too. I've yet to find the cause or pin it to any one thing. I just upgraded nvidia drivers to the latest version today. I'll see how that goes. |

We'll see how it goes. |

It is, but as I said, computer is basically idle, other operations are as fast as usual, just drawing stuff is completely wrecked. |

kill it and try again, it has a mind of it own. _________________ Only two things are infinite, the universe and human stupidity and I'm not sure about the former - Albert Einstein |

Out of curiosity, does an xterm with 'top' running give any clues?
Some memory leak causing swap to fill up?
Some process with high cpu? _________________ ...Lyall |

As I said in 1st post, it's a NO for each question
Everything is looking good, but drawing sucks hard.
I made few steps with positive result:
turned off nepomuk (but I doubt it's that)
changed widget theme for gtk and qt from oxygen to qtcurve,
updated qt to 4.8.3
It's acceptable now, but still, not as instant as I used to have in GNOME.
When I figure something more, I'll let You all know.
Cheers. |

Actually, you didn't answer about the swap and memory usage.

I leave my system on for weeks at a time, and have not noticed any slowdown in KDE.
I'm currently running KDE 4.9.1 and QT 4.8.2
Its very quick and responsive! _________________ "The problem with quotes on the internet is that it is difficult

Could be nvidia trouble. On my >3yr aged ThinkPad with intel driver there's no such thing as slowdowns even after >1d uptime. |

I am getting that on one of the machines as well, after series of recent upgrades to 3.4.9, xorg-1.12, nvidia, and kde-4.8.3
What I see is that X windows is continously running at ~6% and so is konsole at ~6%, even if nothing is done (I am away from office and looking through ssh). X windows managed to use up over a day of CPU being last launched on September 5th.
Close and reopenning fireforx cures a feel of lag for sometime, but then it returns.
And, now to think, it is accompanied by bad gtk perfomance (say menus in acroread and firefox you sometimes have to hover the mouse to redraw),
so perhaps it is gtk engine after all. This started to happen somewhere in the beginning of summer
X (but seems not konsole, and I do not feel any lag) is also happening on my old home nvidia desktop, but not indeed on my intel laptop (with same kde/kernel)

Hmm, It seems only nvidia users reporting this problem so far.
I'll try nouveau later - for lack of better ideas.
BTW. any of You using infinality font patches? |

All right, I picked up new trail But it's yet to be confirmed.
I'm using Eclipse for like 90% of time, so I might not notice it at first, but when I restart it , all going back to normal - for some time. Then this stuff happens again.
So, when I'm in a situation when switching tabs in eclipse editor takes up to 5-7 seconds, I noticed X process CPU usage spikes to 100% and holing until another tab loads.
Any of You with similar problems are using eclipse or other java app? |

I am experiencing this with firefox, as dmpogo reports above. Closing and reopening firefox takes care of it for a while. However, for me the problem gets worse over the course of days rather than just an hour, so it is less of an issue (perhaps a question of hardware?). I also found that closing tabs from certain web sites helps (javascript issues?) even without restarting firefox.
I run eclipse occasionally without any slowdowns but perhaps i do not run it for long enough to see any.
But i am not sure this addresses ^marcs's problem because he should be having the same issues under Gnome, shouldn't he, and he says he doesn't... |

Same here, it seems just some tabs are offending |

OK guis, I'm 90% sure it is media-libs/freetype with "infinality" USE problem , mainly manifesting itself in java stuff. I turned it off and going without problems for 3 days now.
As for firefox problems I can't confirm anything - I'm using Chromium. |

Ok, it's not infinality patches. This still happens.
I think I'll just wait. |

I've changed GTK style from Oxygen into default, build-in, raw, win95 like, "my phone have better widgets" - Raleigh style.
Running OK for week now.
Maybe anyone else want to test it too. |
