[Samba] smbclient transfer speed on solaris

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 at asp1dbrac012:~# egrep -v ^'#|;' /etc/sfw/smb.conf
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 at asp1dbrac012:~#
any help is appreciated,
