Comment 32 for bug 810606

Hi all, my test: copy file from Ubuntu to WinXP and viceversa. File is Ubuntu ISO 733 mb. My network is a wi-fi with about 20 MB transmission speed from PC to router and 100 MB transmission from router to Ubuntu Server. This is my modinfo cifs:

~$ modinfo cifs
filename: /lib/modules/2.6.38-11-generic/kernel/fs/cifs/cifs.ko
version: 1.71
description: VFS to access servers complying with the SNIA CIFS Specification e.g. Samba and Windows
license: GPL

srcversion: 25ACAA091644A0398406E12
depends:
vermagic: 2.6.38-11-generic SMP mod_unload modversions 686
parm: CIFSMaxBufSize:Network buffer size (not including header). Default: 16384 Range: 8192 to 130048 (int)
parm: cifs_min_rcv:Network buffers in pool. Default: 4 Range: 1 to 64 (int)
parm: cifs_min_small:Small network buffers in pool. Default: 30 Range: 2 to 256 (int)
parm: cifs_max_pending:Simultaneous requests to server. Default: 50 Range: 2 to 256 (int)
parm: echo_retries:Number of echo attempts before giving up and reconnecting server. Default: 5. 0 means never reconnect. (ushort)

I'm usng Ubuntu 11.04 server with latest Kernel 2.6.38-11. This is my speed transfer:

sudo dd if=/media/DISCO1/iso/ubuntu-9.04-desktop-i386.iso of=/media/Prova
1431464+0 record dentro
1431464+0 record fuori
732909568 byte (733 MB) copiati, 36,3641 s, 20,2 MB/s

where /media/DISCO1/iso... is my raid HD and /media/Prova is a WinXP directory. My speed transmission is in line with my network speed (24 MB/s). I have removed all configuration parameters to do these test. I don't think this is a bug, but it is a consequence as the cifs.ko module is compiled. Let me know your comments, many thanks.
