Chris Moore, could you please confirm this issue exists with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ . If the issue remains, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:
apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Summary changed: - RTL81xx cards: CIFS is slow to read from, and choppy to write to, compared to smbfs + CIFS is slow to read from, and choppy to write to, compared to smbfs ** Tags added: latest-bios-v1.08 needs-upstream-testing ** Tags added: dapper ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/46081 Title: CIFS is slow to read from, and choppy to write to, compared to smbfs Status in “linux” package in Ubuntu: Incomplete Bug description: I recently started using an old USB1.1 network interface with dapper, and have been having problems reading files from a remote Windows machine on the LAN. I can download packages from the ubuntu repositories at speeds up to 600Kb/s, but from the local cifs mount I am only getting something like 100Kb/s. Also, when I try to copy a large file to a cifs mount, the system starts running very slowly, even the mouse pointer keeps getting 'stuck' for a few seconds at a time. I would like to continue using cifs, since it works with large files better than smbfs, but it's currently not very usable. Using 'smbfs' instead of 'cifs' to mount the remote Windows share fixes both of these problems, and gets my something in the region of 700Kb/s in both directions, which is approaching what I would expect to be able to achieve with a USB1.1 interface. The 'smbfs' mount looks like this: //192.168.1.12/d on /mnt/breezy/home/chris/smb/server/d type smbfs (rw) The 'cifs' mount looks like this: //192.168.1.12/d on /mnt/breezy/home/chris/smb/server/d type cifs (rw,mand) I can't find any documentation for what the 'mand' option does, but I didn't specify it when mounting. I ran 4 tests, both reading and writing a large file using both smbfs and cifs. Here's what happened: 1. reading from smbfs: reads a steady 700Kb/s (14M in 20s) 2. writing to smbfs: writes around 700Kb/s (14M in 20s) 3. reading from cifs: takes a couple of seconds to read anything at all, then reads at about 100Kb/s (2.2M in 20s) 4. writing to cifs: starts very fast, but then system gets choppy, the mouse pointer freezes regularly. note the 8 second lock up from 23:52:27 to 23:52:35. After killing the 'cp' command, it doesn't die for a long time, output is still going on - some buffer is being flushed to the network I guess. Writes around 700Kb/s on average. Here are transcripts of the tests I ran: .------------------------------------------------------------------------ | 1. reading from smbfs `------------------------------------------------------------------------ $ sudo mount -t smbfs -o password=,uid=chris //192.168.1.12/d ~/smb/server/d $ cd /tmp/tmp;
