Let your kubuntu/kde system take up less memory and run faster.

Let your kubuntu/kde system take up less memory and run faster. 2g+ memory can ignore ... Usually after this, the extreme point of about 170MB of memory, is usually about 300MB memory. One of the many development goals of the KDE 4 series is the ability to run smoothly on computers with 256MB of memory. (KDE moment-in work on Consolidator whit 256 MB ram+)

With the latest version of KDE4

The newer the better, including the Kubuntu version.

Do not use Plasma, control style, window decoration themes based on SVG images

The default Oxygen/air style theme uses SVG graphics technology extensively, making the appearance very smooth and natural, but consumes a lot of memory and CPU time. Switching to other lighter-weight topics can save resources, such as plastique, cleanlooks, etc. Plasma topic to try Aya. Window decorations are available in plastic (Plastik).
