Kubuntu uses too much Ram

[Dude-]

I'm new to the whole Linux buisness, even so i installed Kubuntu 6.06 LTS whitout much trouble
installed MP3 codec's dvd support and alot of other usefull prog's ,

the only thing is that Kubuntu uses over 480 mb ram out of my 512 even when nearly nothing is running. i don't think that's normal,

here is a screenshot of it.

p4 3.06 Ghz
512 mb ram
9700 ati video card

the only problem is the ram usage
does anyone have an idea what my problem could be ?

Re: Kubuntu uses too much Ram

Hi,

Don't worry. A lot of the available ram is cached (disk cache) when unused.
Reboot and check again.

On my system: free -m =

total used free shared buffers cached
Mem: 1010 646 364 0 68 410
-/+ buffers/cache: 166 843
Swap: 1576 0 1576

Re: Kubuntu uses too much Ram

Hi,

In fact it's quite normal behaviour for a linux, as it's a memory OS compared to windows which is a file OS. So in fact your system is eating slowly all memory but managing it by itself... So for you it's full, but when you're launching a new application, it's just not using a lot more... no ?
At least, if your system is not using swap so it's good sign, for example :
Laptop with 792 MB : use all memory, 10M of swap
X2 64bit 1GB : use 1GB, 0 swap
