Bug Description

I am experiencing very slow file transfers when using Dolphin to connect to a Samba server on my network.

Here is the file I am transferring:
wxr--r-- 1 legodude users 734013440 2009-02-06 13:55 testfile

To establish a baseline speed I used FTP:

FTP:
get:
734013440 bytes transferred in 20 seconds (35.47M/s)
put:
734013440 bytes transferred in 17 seconds (40.23M/s)

To get a baseline for how Samba should be performing I used smbclient:

smbclient:
get:
~20s ~35 MB/s
put:
~52s ~13.5 MB/s

Now using Dolphin. Transferring from the server to the client is not bad, but client->server is ~100x slower than it should be.

DOLPHIN:
get:
~19.3 MB/s
put:
~350 KB/s

I am using Jaunty with all of the latest updates as of the morning of Feb 6, 2009.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* What version of Dolphin are you using?
* Is the problem reproducible? Has it worked fine on earlier versions of Ubuntu?

This will help us to find and resolve the problem.

Thanks

Sorry, I thought I was clear about the version when I said I was using the latest Jaunty. I am using Dolphin 1.2/KDE 4.2.0.

I also wasn't sure if I was supposed to mark this as a problem in the Dolphin package as I thought it might be somewhere else in KDE.

The problem is reproducible on this system. My other jaunty system is sick at the moment so I cannot test it. I have not used Ubuntu prior to this so I cannot speak to performance in earlier versions.

Thanks
