Hi, I'm currently seeing a serious performance problem with a cifs-mounted WinXP share, and I've not found any reference to it yet. Basically my hardware is a desktop with Windows XP. VMWare server is installed and I have Ubuntu 10.04 as an image. The ubuntu VM cifs-mounts this XP share that's called 'ControlPanel'. This has been running just fine until yesterday morning then I was prompted to install an updated kernel and reboot. Since then, I can mount the share, I can look in the files and do everything normally, except run phpunit which now runs dog-slow. Previously, I would expect 15-30s for total phpunit execution. Now, it's between 2m30s and 5m30s. I traced the code through and found it to be trying to load the files up. syslog shows every fifteen seconds: Jul 2 16:09:13 ubuntu kernel: [ 1033.820126] CIFS VFS: No response for cmd 50 mid 6469 Jul 2 16:09:27 ubuntu kernel: [ 1048.779718] CIFS VFS: No response for cmd 50 mid 6593 Jul 2 16:09:42 ubuntu kernel: [ 1063.816102] CIFS VFS: No response for cmd 50 mid 6722 Jul 2 16:09:57 ubuntu kernel: [ 1078.787182] CIFS VFS: No response for cmd 50 mid 6855 Jul 2 16:10:12 ubuntu kernel: [ 1093.820243] CIFS VFS: No response for cmd 50 mid 6991 Jul 2 16:10:27 ubuntu kernel: [ 1108.793428] CIFS VFS: No response for cmd 50 mid 7120 Jul 2 16:10:43 ubuntu kernel: [ 1123.828834] CIFS VFS: No response for cmd 50 mid 7260 Jul 2 16:10:57 ubuntu kernel: [ 1138.798723] CIFS VFS: No response for cmd 50 mid 7395 Jul 2 16:11:13 ubuntu kernel: [ 1153.836951] CIFS VFS: No response for cmd 50 mid 7544 Jul 2 16:11:27 ubuntu kernel: [ 1168.803846] CIFS VFS: No response for cmd 50 mid 7677 Jul 2 16:11:43 ubuntu kernel: [ 1183.844863] CIFS VFS: No response for cmd 50 mid 7829 Jul 2 16:11:57 ubuntu kernel: [ 1198.808690] CIFS VFS: No response for cmd 50 mid 7955 Jul 2 16:12:13 ubuntu kernel: [ 1213.840801] CIFS VFS: No response for cmd 50 mid 8073 Jul 2 16:12:27 ubuntu kernel: [ 1228.813492] CIFS VFS: No response for cmd 50 mid 8219 Jul 2 16:12:43 ubuntu kernel: [ 1243.844349] CIFS VFS: No response for cmd 50 mid 8338 Jul 2 16:12:57 ubuntu kernel: [ 1258.817835] CIFS VFS: No response for cmd 50 mid 8425 Jul 2 16:13:13 ubuntu kernel: [ 1273.852591] CIFS VFS: No response for cmd 50 mid 8557 Jul 2 16:13:27 ubuntu kernel: [ 1288.822119] CIFS VFS: No response for cmd 50 mid 8687 Jul 2 16:14:26 ubuntu kernel: [ 1347.512906] CIFS VFS: No response for cmd 50 mid 10970 Jul 2 16:14:43 ubuntu kernel: [ 1363.848978] CIFS VFS: No response for cmd 50 mid 11040 Jul 2 16:14:58 ubuntu kernel: [ 1378.833956] CIFS VFS: No response for cmd 50 mid 11112 You get the idea... I downgraded to the previously installed kernel without any improvement. I upgraded to http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/linux-image-2.6.35-999-generic_2.6.35-999.201007021009_i386.deb again without any improvement. Using wireshark I noticed lots of QUERY_PATH_INFO requests but I have no idea what is normal. When connecting a remote 9.10 machine to my share, I again see the QUERY_PATH_INFO but the performance is as expected - much improved. I've raised a ticket with Ubuntu which I've been making notes in: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/600565 Can anyone help or give me further instructions for debugging this? I'm working at a snails pace otherwise :( FYI my smbfs version is 2:3.4.7~dfsg-1ubuntu3.
