File transfer speed issue

Wed Dec 12 13:55:06 GMT 2001

Oh forgot:

smb.conf:

I have tried with and without most options below with no difference in performance.

 [global]
        workgroup = WORKGROUP
        server string = Samba 2.2.2 Server
        interfaces = eth0
        security = SHARE
        log file = /var/log/samba/log.%m
        max log size = 50
        read bmpx = Yes
        announce version = 5
        socket options = TCP_NODELAY SO_RCVBUF=65536 SO_SNDBUF=65536 IPTOS_LOWD_LOWDELAY
        load printers = No
        os level = 35
        lm announce = True
        preferred master = True
        domain master = True
        wins support = Yes
        guest account = anonymous
        create mask = 0644
        hosts allow =

[root]
        comment = temp folder
        path = /tmp
        read only = No
        guest ok = Yes
        fstype = FAT32
