First, by "very large files" I'm thinking tens of terabytes. Second, there's only a benefit to jumbo-frames if EVERY device between the two endpoints supports it. Chances are, the end-user's desktop doesn't support it (or doesn't have it enabled), or you've got an old switch at a tower, or someone at a co-lo on the other coast forgot to enable it. If any piece of gear between the two doesn't support jumbo frames, your giant packet will get fragmented anyway, and you may end up with worse performance. Obviously, you want to bench-test for your particular application, but outside of some specialized environments (like Internet2) jumbo frames don't really win you very much. David Smith MVN.net
