[Samba] big performance difference between Samba and FTP

I have been using Samba for a while but have not been able to get it to
work as fast as possible. While I manage to transfer 9MB/s (read/write)
over a 100Mbit network using FTP I can only get up to 5.5MB (read/write)
I have Samba-2.2.8a installed under Suse 8.0.
The machine is a Celeron 600 with 512 MB RAM and the drive I am copying
the data to and from is an IDE drive (60GB IBM).
When transferring files using Samba, the CPU usage for the smb process
goes up to 60% but never maxes out the CPU.
Since I pretty much rely on Windows shares on my network I would like to
know what the cause could be for the significant performance loss under
Increasing "SO_SNDBUF=" or "SO_RCVBUF=" did not improve performance,
"deadtime=" and "max xmit=" also did not change anything significantly.
The smb.conf globals look as follows:
log level = 0
socket options = TCP_NODELAY SO_SNDBUF=8192 SO_RCVBUF=8192
deadtime = 15
client code page = 437
workgroup = HS18
server string = File-Server
interfaces = eth2
encrypt passwords = Yes
os level = 99
preferred master = Yes
domain master = Yes
wins support = Yes
hosts allow = 192.168.0.0/255.255.255.0
printing = lprng
Any help would be greatly appreciated,
If all you have is a hammer, every problem looks like a nail.
