I'm running into this issue myself. I just loaded up a new application
on my linux system that is being bottlenecked by the smbfs I/O issue.
I've been reading through these threads (among others) I've done as many
tweaks as I can. As one person above tested using smbclient vs
smbfs/cifs you can

Same problem here on Oneiric.
The upload speed is good (11.X MB/sec), but the download is pper (5.X
MB/sec) on a 100mbps LAN.
I try all parameters of cifs module.

Tried on same system using windows 8 -- Windows 7 resulting in 40% link
utilization (50MB/s)
Windows 8 thus has double the cifs speed ubuntu mount.cifs has at the

Hello Bohdan
excuse the delay, but I was on vacation. The 2.6.38.11 kernel should be
available in the Ubuntu repositories 11.04. However, the cifs seems to work
much better now. If, after some time, there will be no further problems, I
shall put the status of the following bug as invalid.

Massimo,
38-11 is still proposed, I am syncing with backports and there is 38-10.
How it will be dealt with required configuration with respect to the
ubuntu istallation?

Hello Massimo,
I think we still speak about different things. My solution has two
halves:
1. Adding required configuration parameters, which improve performance. In this
step I agree with you completely
2. Upgrading from 2.6.38-8 (got it from main) to 2.6.38-10 (got it from
backports) which
Hello Bohdan,
You have right about the patch apply to kenrel 2.6.38-10:
* cifs: change bleft in decode_unicode_ssetup back to signed type
- LP: #788691
* cifs: check for bytes_remaining going to zero in CIFS_SessSetup
- LP: #788691
* cifs: sanitize length checking in coalesce_t2
Hi Bohdan
I understand what you mean and I think I don't explained myself well. This is
holding me back from confirming this bug is that, how could you see yourself,
playing with the parameters set by the programmer, for the module cifs.ko, you
can increase or decrease the speed of transfer.
cannot confirm this. On my system with modifiers at cifs.ko and mount options:
733964288 bytes (734 MB) copied, 40.3041 s, 18.2 MB/s
without cifs.ko (CIFSMaxBufSize)
734793728 bytes (735 MB) copied, 57.1226 s, 12.9 MB/s
without mount options(rsize=32768,wsize=32768):

Hello everyone. I must admit that what is strange is that each of you
has a different result about the speed tests:
@ Boletis Georgios said to reach about 60MB out of Nautilus and 8-10MB in

@ Bohdan says that no more than 4-5MB;
@ zzarko having reached the 7-8MB;
@ Ubuntu Uefi User
I can ask to you to do the command cat /proc/fs/cifs/DebugData (except
@Bohdan who has just post the result). This command is necessary to
understand the version of cifs module in use in your ubuntu box. Thanks.
