It's it normal that OES2 SLES10SP1 takes al lot of memory and is very slow?

We installed this:
- eDir
- ncp
- nss
- netstore (don't use it yet)
- pure-ftpd
- lum
- samba

This server is a guest xen on an other SLES10SP1 host.
We gave it 2 cpus and 6 GB ram.
It using nearly 6GB af ram yet.

Any suggestions to fix it?
