samba - Feb 2004 - Samba Slow, and I have high Quality NICS

I have SLOW file transfers across samba to my Windows Server 2000 domain.

I am using a built in 100bT Intel Pro NIC, I have tried the built in gigabit
NIC and a PCI 3com, all with the same results.

Using iperf, I get about 45-90Mb of bandwidth from my PC's to my samba
server.

I can pull it up by \\servername <file:///\\servername>  or \\ipaddress
<file:///\\ipaddress>  with out any issues. I can ping servername
successfully.

It is taking about 15 minutes to just pull across a 10mb file.

I've seen a lot of complaints about this on the web via "google"
but no one
seems to have conquered it.

Anyone have a fix for this? I would owe you a steak dinner.

of course, you didn't say where...

most of the time, this is caused by 100 baseT switch with 4 wire (2
pair) cables - cat 3 cables on cat 5 connection. causes hell with
auto-negotiation.

what is output of ifconfig?

Anson,

  Can you try setting the NIC to 10Mbps/Half
 and Full Duplex to see if the transfer times
improve?

I put in a switch a while back , and have a 
Lexmark Optra printer with a NIC capable\
of 10/100. The LAN cabling is shielded CAT3.

  The Optra would negotiate to 100Mbps with
the switch, but printing took forever.
I locked the NIC at 10Mbps, and normal
printing resumed immediately.  Sounds a little
like your problem.

I suspect something similar on your
connection;  CAT3/CAT4 cabling or bad cabling,
and the NIC negotiating a higher connection
speed than is actually supported.

Hope this helps.
Jim
