Hi Peter,
I am having a similar situation to what you have described in your
post. Were you getting normal throughput from the NIC in question when
using protocols other than SMB? For instance I can't copy a 90MB file
from the samba server but I can download it via http in no time.

Hello,
I finally got round to running the tests with other NICs, and I think I've
solved the problem!
With a 3c905B I get:
SMB - 7.2 MB/s (45% CPU usage)
FTP - 9.9 MB/s
And with a DEC 21140 based card I get:
SMB - 5.8 MB/s (36% CPU usage)
FTP - 7.5 MB/s
When compared to what I was getting (1.6 MB/s) with the NIC that comes with
the server (TLAN - NetIntelligent 10/100) it's a HUGE difference!!!
Now I think that it's just a question of tweaking the smb.conf file to get
the SMB rate closer to the FTP rate!
So it turns out that there is nothing wrong with FC3 or Samba 3, it was just
my old hardware! It's amazing what a DMA capable NIC can do for the overall
system performance.
Peter.
