to much consumtion of ram?

Hello,

i installed NWDS 2.0.9 and WAS 6.40 JAVA (only) SP09 on a notebook with 512MB RAM.

If I start NWDS and WAS the swapfile is about 1,03 GB big and the whole system is very slow.

Are there possibilities to lower the consumtion of ram? I think the highest part is in the j2ee server.

Thanks for help,

André
