The reason this becomes more profound on these large-cache systems is typically because the data sizes are larger in addition to the things mentioned above.

By far, the largest benefit here is for larger Sql systems that can benefit from additional memory space via AWE mechanisms.

Can you try it? The only reason it would fail is if it had bit components, which are no longer supported in x David Yu David Yu 1, 7 7 silver badges 14 14 bronze badges. The 16gb limit is not going to be a problem in this case as the server is dedicated to running this process and the program itself is already nearing its internal limits.
