View Full Version : KDE 4.3 is great. But it uses too much memory.

Glad to say that 4.3 was stable and fast all day, but at the end of the day memory usage climbed steadily. Using 1.5 GB of the 2 GB total memory...

KDE4.3 is to big, to complicated. It seams like kde4.3-l10n does not support zh_CN.GBK, only support UTF8.

i am using xfce4, it's easy, light

But, is that wired memory (actually in use by apps/libs) or cache memory (file cache, buffer cache, VM cache, etc)?

Remember, "free" memory on FreeBSD is wasted (unused) memory. The kernel tries to use any "free" memory for cache. On a properly working FreeBSD system, the "free" memory should be near 0.

Also, remember that KDE re-uses a lot of shared libs/data, so the memory usage reported by top will not be an accurate reflection of the actual memory usage. Top doesn't show shared memory resources correctly.

There are several blog posts on planet KDE that cover this topic, and how most "memory checkers" get it wrong.

Yes. But KDE 4.2 uses much less memory than KDE 4.3.
There are many "kdeinit4" processes which use a lot of memory.

Yes, and each of those processes is sharing something like 90% of the memory, so it's not actually using as much as you think. Which is my point.
