Are there any good tips for optimizing KDE4 memory consumption?

It feels like a memory hog, even when I have 4GB of RAM and i5 CPU it feels heavy.

I disabled all effects but still it feels heavy and consumes twice more memory then Gnome.

Any points for optimization of KDE4 (not Ubuntu in general)?

Try this package:

sudo apt-get install kubuntu-low-fat-settings

It is specifically designed to minimize ram consumption and speed up the system as much as possible.

Nice, thanks. It saved me 100MB of memory, now it is 625 against 725... – Artyom Dec 10 '11 at 19:52

I do not think it is a memory issue in machine with 4 gb RAM. It is more likely to be a graphics card driver issue. What is your graphics card and your current driver? And KDE version matters, of course among other parameters like running background processes etc.

Graphics card is Intel, so it should be very well supported, also I'm talking about Ubuntu 11.04... I don't know the exact version. After all it is memory hog even in "effects-free" configuration. – Artyom Dec 18 '11 at 7:35
