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

Even with the existing suggestions I still found JCIFS too slow to stream videos over my local network. It seems to be do with the overhead per buffer read from the network, even reading into large buffers JCIFS itself had a limited buffer size which was the problem.

If you look in https://jcifs.samba.org/src/patches/ there's a patch, LargeReadWrite.patch. You'll need to apply the patch and rebuild the code to use it, but it made a big difference for me.
