I have a Windows 2003 machine(2) with a share mounted on a Freebsd
machine (1) via mount_smbfs

Hardware
Machine 1

FreeBSD pcmarpxy.mine.nu 4.9-STABLE FreeBSD 4.9-STABLE #1: Fri Jan 30
23:33:38 CET 2004 root@pcmarpxy.mine.nu:/usr/obj/usr/src/sys/MARK
i386
PIII 650, 392mb ram
system : ata-100 5400 disks on builtin ide
data :- 2 ata-100 disks on a promise ata card running under vinum
(software raid) raid 0
- real men always run raid 0 :-)

BSD is recently cvsupped and compiled etc...
samba Version 3.0.1

Machine 2

Windows 2003 all patches.
PIII 500 with a promise atx raid card and a
pair of 30gb ata-100 5400 rpm. (also raid 0)

The machines are connected via a switch running 100mb all interfaces,
ports are
manually set to 100mb full duplex, neither machine is exactly
overloaded.

I backup to machine 2 (40gb) via an smb mount to a Windows 2003 server.

with smbfs
167604556 bytes sent in 8m.15.133 (330 Kbytes/s)

With ftp
167604556 bytes sent in 15.06 seconds (10.62 MB/s)

With samba (from samba share on Freebsd box to Windows 2003 box)

167604556 bytes sent in 35.06 seconds (4.56 MB/s)

 
this is something of a disparity!. Anyone got any ideas....
