Have you got 4GB of PHYSICAL memory in your computer? If not, /3GB + /LARGEADDRESSAWARE would be quite useless (in terms of a performance increase anyway) and you'd be much better off just running straight off the disk. Besides, the way the garbage collector in .NET works, you actually need a fair amount of extra virtual memory than what you are actually using. So even with /largeaddressaware, you're probably not going to get very close to the 3GB limit because of the overhead. Of course, if you have a 64-bit machine, things are a little different... Dean.
