[Samba] Is Samba Slow?

[Wade Winright]

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...

Importance: High

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!
