[jcifs] incredibly slow transfer speed

[Torben Wölm]

Hi Wade

I don't understand much about virtual servers, but I know there's no problem connecting to remote virtual servers. Here are some suggestions:

1) Try connecting to a share on your local machine (not with //127.0.0.1/share but with the right IP address) to see if that is also slow.

2) Use something like Ethereal on the Windows 2000 virtual server to see if that gives a clue about what is going on during the .5 second delay.

Kind regards
Torben
