Have been using this shiny new 4.3 for a week now. But this performance degradation was seen even with 4.2.4.

When running a KDE session continuously for two/three days, without any sleep/hibernate stuff, with time, the performance degrades drastically. Each and everything slows down (~.5 to 1 sec delay - which is quite pronounced). E.g. minimize windows, switching windows, starting applications, .... (I do have some of the bling-bling effects on)

Solution: close everything, logout and log back in - everything seems fast and snappier again - but only for two more days...

Does anyone see this behavior? It is quite bothering, though not as annoying as 4.0/4.1 I was hoping 4.3 would be more optimized and stable, but I am disappointed.

Kill plasma and launch again. Probably this help.

If you have Nepomuk enabled disable it if you are not using it.

And how would one do that?

Is this System Settings > Advanced > Desktop Search? If so, then I have always kept this disabled.

Plasma can be restarted by doing the following in Konsole:

Code: Select all

kquitapp plasma-desktop && sleep 15s && plasma-desktop &

Thanks, bcooksley. Thats a handy alias. I had to logout/login a few times today due to plasma crashes, so my "performance counter" is reset now. If everything goes fine, then another two/three days run now...

Something else you might want to consider: open Konqueror, go to Settings --> Configure Konqueror --> Performance. Under, "Minimize Memory Usage" select, "Always" and, if your system is going slow even without using Konqueror, tell it not to preload instances of Konqueror. It will mean that Konqueror takes a little longer to load, but it doesn't leave its own background process either.

Madman: I have 4GB of ram and I think that activate this option must don't be necessary. On the other side the options are:
- Never
- For file browsing only (recommended)
- Always (use with care)

I read "recommended" and "use with care" and my decision was taken .

But I don't use konqueror, because past problems with flash and cookies, and my solution for performance issues was a cron job that kills plasma every day at 7:00am.

Aah. Strange. Plasma doesn't do that to my laptop, which only has 1.5GB of RAM...

Yes, amazing, I never hear about users with Plasma memory and CPU problems related, maybe is an urban legend like the guy that could see a Plasma crash. I'm joking .
