[linux] Multi-port NICs?

[Garrett Cooper]

    Do you use the 8 Kb send/receive option in Linux and the 8 Kb options on
the Samba server? You most likely do, but that's the part that usually hangs
up a lot of people.
    About the SFU NFS.... yeah... you have to install both the server and
the client and even then it's sort of kludgy in XP. My experience with it in
2k server was much better, but I always have issues when I boot to XP once I
upgraded (most likely something about the client not being able to contact
the user mapping service or some such junk even though remounting the NFS
share works fine). I did update my passwd and group files and it did seem to
work a lot better though and hasn't complained since I did that. Also,
proper user/group mapping plus making sure the UID is the same for the Linux
share as it is for the Windows user mapping seems to make a big difference
in error messages =\...
    I will say that I do notice a big difference between NFS and Samba as
far as filesharing is concerned. With 2 machines containing 7200 RPM
harddrives I was able to get a full 11 MBps connection out of them whereas I
had issues exceeding 2.5 MBps on Samba. May have been my send/receive buffer
setting at the time, but it did seem that even after I modified that setting
Samba still didn't run as quickly as NFS did.
    Also-in response to David-I figured as much about the networking
considering that a lot of standards and optimizations do come out of the BSD
camp in terms of IP and TCP.
