Hello Friends...

I m a Newbie..I Installed Suse 10.1 to my Laptop ...

I got RAM of 512Mb

I Installed 1025MB Swap also ....

But Alwyz my RAM usage is around 490MB/512 .... wher as SWAP is 0/1025MB

Is ther any problem with my SWAP ?

How are you checking your RAM usage? If you use free -lm, look at the line that says "+/- buffers/cache:" -- the actual amount of RAM used by applications is in the USED column. Swap is probably not being used because you have lots of RAM left for applications in the FREE column.

What you consider heavy RAM usage seems perfectly normal. I have a system with 2048 MB of RAM that does the same thing (numbers below are in MB)

Code:

[bouchecl@fedora ~]$ free -lm
             total       used       free     shared    buffers     cached
Mem:          2022       1957         65          0          6       1644
Low:           870        817         53
High:         1151       1140         11
-/+ buffers/cache:        306       1715
Swap:         1027          0       1027

As you can see, 80% of all RAM is used as cache, and the system consumes only 300 MB of actual RAM. The swap hasn't been touched. If you repeat the experience on your own system, you'll probably end up seeing the same thing.

Had the same issue with Suse 10.1.
Did't have any swap partition but 2 Gigs of RAM and 10.1 used way to much RAM than needed.
Installed 10.2 and it works like a charm, uses few RAM liked it did with 10.0.
