memory-usage

We're using an Ubuntu 9.10 server to transfer Ghost-image files. We configured it only with Samba. And the DOS-clients connect to Samba. The latest updates are installed and so far the servers is running fine.

When we image 10 pc's with the same image of 2 files of 2GB there's no disk activity. Everything is loaded in the RAM. There's 4GB in the server.

But when we use 2 pc's with 2 different image files of 500 MB (8x) files then there's a lot of continuous disk activity. The speed is lower.

So it seems that Ubuntu doesn't cache more then one big file. Are there settings to change this behaviour?
