We have a DOS based database program which simply cannot be discarded. Because we're stuck with it, I accepted it, killed the NT server and setup FreeBSD/Samba. I'm running Samba 2.0.7 and FreeBSD 4.2-STABLE. Our database is 300-400 megs, and it's not the only shared EXE on my Samba server. We have timekeeping and other software that all execute directly from the Samba shares. I don't really have any issues, except that the guy who wrote the DOS program decided he liked reading data one byte at a time, so the overhead absolutely kills my bandwidth. I get around 200,000 bytes per second. I increased NMBCLUSTERS, and now, at times, the connection will peak at 700,000 bytes per second. I'm using a 100BaseTX Switch. Our server is an IBM Netfinity 3500 Dual Pentium III 500 with 256megs ram and UltraWide 7200rpm SCSI. I've tuned my smb.conf file with settings shown on the Samba website and in SPEED.txt and SPEED2.txt. My suggestions to you would be: (1) Is Samba acting as your master browser ? (You want it to) (2) Is Samba's WINS server running ? (You want this too) (3) Read speed.txt and optimize your smb.conf (4) Are you using a hub or a switch ? For this kind of DOS application sharing I've found that a switch makes all the difference in the world. (5) Rather than reading the stupid message Windows gives you about Network Busy, go to /var/log and read the log.[client] file for the client you're using along with log.smb and maybe even log.nmb.
