Subject RE: Max possible ram usage
Date Wed, 21 Jul 2004 13:03:30 GMT
Hi,
I actually don't think any stable VM implementation at this time can
address more than 2GB.  But I'm sure they're all working on it and we'll
have 16GB and more soon enough.

Don't just use all this memory because you have it, though.
