Hi, I am trying to transfer data from a win2003 (OS=[Windows Server 2003 3790 Service Pack 2] Server=[Windows Server 2003 5.2]) to a solaris 10 (sun4v arch). smbclient version is 3.0.25a. Although this is a switched gigabit network (no firewalls/routers inbetween), and even jumbo frames are set up on the relevant NICs on both sides, I cannot transfer more than 35mbyte/s (40 peak) with smbclient. The command line is: smbclient //<TARGET_IP>/<sharename> -I <TARGET_IP> -A <auth_file> -c'prompt; ls ; mget *;' The diskwrites on the solaris box cannot be the bottleneck, tested it, can write way more. I was wondering if anyone had an advice regarding performance tuning? According to our win-admins they can provide easily 60mbyte/s between their windows servers. my smb.conf is pretty basic: root@asp1dbrac012:~# egrep -v ^'#|;' /etc/sfw/smb.conf [global] server string = Samba Server security = user log file = /var/samba/log/log.%m max log size = 50 socket options = TCP_NODELAY dns proxy = no root@asp1dbrac012:~# any help is appreciated, wbr, charlie -- Karoly VEGH - System Engineer Unix bwin Interactive Entertainment AG IT Operations Unix Tel: +43/664/8508069

The command line is:Do you have a chance to try smbclient from the 3-2-test git branch? I've done some considerable changes to speed up smbclient mget. You can get a current tar.gz via http://repo.or.cz/w/Samba.git?a=snapshot;h=refs/heads/v3-2-stable;sf=tgz or you can check it out via git yourself.> root@asp1dbrac012:~# egrep -v ^'#|;' /etc/sfw/smb.conf > [global] > server string = Samba Server > security = user > log file = /var/samba/log/log.%m > max log size = 50 > socket options = TCP_NODELAY > dns proxy = no > root@asp1dbrac012:~#Just try removing the socket options completely :-) Volker -------------- next part -------------- A non-text attachment was scrubbed...
