It can handle 2.7 - 3GB of RAM if you have at least 4.5GB installed,  
probably 5. So it would probably help quite a bit, in fact I suspect  
that's your problem: you have so many samples loaded into RAM that  
your system is using virtual memory (meaning the hard disk). That  
assumes you have the EXS' virtual memory turned on, which means disk- 
streaming.

If that's not it, I think you have to watch Activity Monitor while  
you're adding these instruments one at a time to see what's breaking  
the camel's back. I'd also try using the built-in audio so you can  
rule out it being an RME issue.
