http://forums.opensuse.org – Hi all. I have the problems with transfer speed between samba and Windows XP clients. 1. samba server configuration: Quad Core 6600 CPU. 4 Gb RAM OpenSUSE 11.2 with kernel "2.6.31.12-0.1-desktop" Samba - samba-3.5.1-1.1.i586 - - - - Test: 4 GB File copying. One file. transfer speed from Samba Server to Windows 7 and XP clients: (Windows clients copy file from Server share -> to local drive) From Server to Windows 7 client 1: 85-90 Mb/sec From Server to Windows 7 client 2: 90-100 Mb/sec From Server to XP1 client 3 75-100 Mb/sec transfer speed from Windows 7 and XP clients TO Samba Server: (client copy file from local drive -> to server Share) From Server to Windows 7 client 1: 12-20 Mb/sec From Server to Windows 7 client 2: 30-35 Mb/sec From Server to Windows XP client 1 20-27 Mb/sec (copying file from Windows local drive to Windows remote share) From Window 7 client 1 TO Windows XP client 1 40-50 Mb/sec From Window 7 client 2 TO Windows XP client 1 50-60 Mb/sec Copying file from Windows 7 client 2 share -> TO Windows XP client 1 show me 100-120 Mb/sec speed permanent. = = = Copying file from Linux hosts to NFS server is stable 50-90 Mb/sec bidirectional. This part of my smb.conf file Code: # version at /usr/share/doc/packages/samba/examples/smb.conf.SUSE if the # samba-doc package is installed. # Date: 2009-10-27 [global] log level = 1 debug level = 0 max log size = 50 #read prediction = true #read size = 65536 #strict locking = No #strict sync = No #sync always = No wide links = yes read raw = yes write raw = yes #max protocol = smb2 realm = some.com # client ntlmv2 auth = yes socket options = TCP_NODELAY IPTOS_LOWDELAY SO_SNDBUF=65535 SO_RCVBUF=65535 winbind enum groups = Yes winbind enum users = Yes idmap uid = 10000-20000 idmap gid = 10000-20000 auth methods = winbind winbind use default domain = No case sensitive = No #client use spnego = Yes #client signing = Yes         workgroup = ???????         server string = ""         passdb backend = tdbsam         printing = cups         printcap name = cups         printcap cache time = 750         cups options = raw         map to guest = Bad User         logon path = \\%L\profiles\.msprofile         logon home = \\%L\%U\.9xprofile         logon drive = P:         usershare allow guests = Yes         security = domain         add machine script = /usr/sbin/useradd  -c Machine -d /var/lib/nobody -s /bin/false %m$         domain logons = No         domain master = No         netbios name = Server         wins support = No #[homes] #      comment = Home Directories #      valid users = %S, %D%w%S #      browseable = No #      read only = No #      inherit acls = Yes Another words: I have very slow WRITE speed when copying file FROM Windows clients TO Samba Share. This is the most problem. Of course i hear many many questions from Windows users. All possible help is very very appreciated. p.s. my books now: SAMBA Documentation Samba speed is slower than Windows native clients connections ? (Distributions)
