[Samba] Is Samba Slow?

I installed samba 2.2 cvs version in a file server. The configuration is:
- AMD k7 1.2Ghz
- Asus kt133
- 3 IBM 7200 IDE HD 80 gb with LVM and Ext2/3 volumenes
- 1gb RAM
- Redhat 7.2 + kernel 2.4.16 + acl patch
- 2 Ethernet Card 10/100 3com (but I only use one. Can I use the 2 
cards? How?)


The problem is: Samba is slow (4,5mb/s) compared with Novell (6mb/s), 
Windows (5.5mb/s) or ftp (8mb/s).
The network benchmark test (netio) that I ran gave me 11.4mb/s
The disk benchmark (hdbench 0.14.1) gave me 30mb/s read and 27mb/s write

With the samba test I used smbclient and smbmount from another linux box 
identical to the server. The volumen was and lvm/ext2 volumen.

I know that samba always is compared with ftp transfers so Why do I get 
only 4.5mb/s if ftp give me 8mb/s?
The current speed (4.5mb) is not acceptable for us because Novell gave 
us better perfomance with less hardware (pentium II 266mhz).

I have a lot of pressure to upgrade the novell server to the new 
hardware (I wish to replace 2 W2k file servers and 1 Novell server with 
this linux box :-)

If I can not speed up samba at least to 6mb/s (Novell time) I'll have to 
return to the novell server. And I don't want to do this :-((

Please help!

I send my smb.conf file.
If you need more information please tell me!

RH 7.2 with certain 3com cards seem to have to be modified, or have the
correct driver installed and then hard coded to 100full. I would run a
"mii-tool" as root to see what your card is running at.
Just a suggestion...

smbclient is not very efficient, and smbmount is even worse.  I think if you
try the Samba server from an actual Windows client you'll find it's
faster
than it is from smbclient.

Yes, but if I put two ethernet with samba in the same subnet, can I 
duplicate the bandwidth? I mean, statistically the half of the clients 
connect to one card and the half connect to another?

I made perfomance test with win95 clients connected to the same switch 
that the samba server. I copy 1gb file from smb to win95 and viceversa:

smb -> win95: 4.04mb/sec
win95 -> smb 4.59mb/sec

These numbers are similar as smbclient, and they ar *far* from 8mb/sec 
of ftp transactions from linux clients.

Any idea?

I'll run perfomance test in w2k machine's and ftp transfers too.
