WebAS 6.4 performance

Hi all,

I'm planning to install Was 6.4 sneak preview on my laptop and I'm not sure if it will be fast enough.

The main lack is in memory. The laptop has 512mb and the minimum is 765mb. The CPU is a Pentium Mobile 1.6Ghz

Will it work (even slowly)? Will it fall and deny any possibility of funcionality?

Is anybody working under minimum ram level? How it works?

thanks in advance,
