Comments: To: "P. Cristian Gugiu" <crisgugiu@YAHOO.COM>

your SAS is 32-bit, so that total memory consumption from SAS session can't
exceeds 2GB, even if you switch to Win7.

Since you have such a big sized memory, you can use them as a buffer folder
for your working datasets, i.e a memory-based library
for example:   libname mymem memlib  "c:\temp" ;
for details, see MEMLIB in OnlineDoc, you will find a lot of tune
parameters to play with.

I see this as the easiest way to boost performance as most of our work are
I/O bound.

There are other optimizations you will consider, especially for MP machine.
