JCIFS: file retrieval is too slow to be usable

Question

I was just testing JCIFS for accessing Windows shares. It is very slow to the point of being completely unusable.

import jcifs.smb.*;

class First {
    publ         


        

Answer 1

In my own case, pushing files TO a Windows share via JCIFS was too slow to be usable.

The solution turned out to be defining the property

-Djcifs.resolveOrder=DNS

The default inclusion of BCAST -- broadcasting a NetBIOS name query to 255.255.255.255 -- was needlessly resulting in a lengthy delay. (Link above de-framed from the top-level API docs.)
