Subject:   SAMBA throughput increases when NIC bandwidth is decreased

I am running SAMBA 2.24 on a FreeBSD 4.6.2 box, a 1GHz PIII with 256MB RAM 
and a nice big, fast scsi hard drive.  My problem is that I cannot get a 
decent amount of bandwidth out of it.  I have tried adjusting the smb.conf 
file, based on SPEED.TXT, but I still cannot draw more than 300 or 400 k 
bytes/second out of it.  I tried scaling its ethernet switch port down from 
100MBPS full duplex to 10half, and the speed more than tripled -- up to 
1200 kbytes / second.  I can't explain this --- help??  I have also tried a 
variety of NICs, from 3com etherlink 905b to Intel EtherExpress Pro100 and 
a D-Link card.  All exhibit similar behaviour, although not to the extent 
of the 3com.

Any suggestions or thoughts?
