Actually, your stats shows v2.5 using 174MB of RAM, whereas v3 uses 215MB

So, v3 is using more RAM, 41MB increase (24% more)

Which engine are you using?

What is your db page size?


I guess I don't think of that as a significant difference. Our Delphi server application running using 16GB of RAM at one location, so 41MB doesn't even raise an eyebrow.
