Hi,

This is a follow up mail about my old mail.  I checked some
configuration recently.  All NIC showed good results
although I experienced very slow file transfer time from
client to server old days.

Last time, I said best NIC card for SAMBA is Intel NIC for
me.  However, all cards look fine now.  Sorry, if you
experienced problems or bought Intel because of my old mail.


Anyway, my experiments are:

I made two files.  One is small.  The other is big.
Basically, I used RAID5 file system on a server.  I copied
files from server or to server through Windows client
machines.  PIII 933MHz machine is Windows 98.  PIII 700MHz
machine is Windows 2000.  Celeron 266MHz machine is Windows
XP RC2.  I also took transfer times to non RAID5 file system
to get brief idea about the cost for RAID5.  PIII933 and
PIII700 uses Intel NICs.  Cel266 uses internal one I don't
remember the manufacture.

The results are below.  All show good results this time.  I
used Aug 18 kernel and samba-2.2.1a from pkgsrc.

  Note: PIII933 shows slow transfer.  I'm not sure why.  I
    exchanged network cable and network card between PIII933
    and PIII700, but it didn't help.  Maybe, Win98 is a
    reason of it.
