smbfs extremly slow in feisty

[Anton Farber]

Binary package hint: smbfs

Transferring files over an SMB network (mounted with mount -t smbfs ...) is relatively slow. I get around 2 MB/s whereas over other protocols (e.g. SSH) I get around 9-10 MB/s. The receivers are various Samba servers, all of them are performing well (7-9 MB/s) with other clients. I already tried to tweak my mount cmd (TCP_NODELAY, SO_{SND|RCV}BUF=8192 etc), unfortunately without any success. I noticed while capturing my network traffic with Wireshark, that - eventhough I specified a buffer size of 8192 bytes - it seems as if only 512 bytes are transferred at the same time (see http://www.sweety.li/tmp/wireshark_smb.png for a screenshot).

I never had this problem with other Linux distributions or lower Ubuntu versions before, so I guess it is nothing hardware related. Nevertheless, you may also find my complete dmesg, an output from lspci and lsmod on the site http://www.sweety.li/tmp

As you can see from the output of my dmesg, something definitely seems to be wrong

What happens when you use cifs?

Hi Chuck,

I'm sorry, I do not use Ubuntu anymore, so I can't test your suggestions.

Ys, Aurel Bodenmann
