RE: Freebsd 5.4+samba
I do not think polling will help him. I've dealt with those Dells before, if I am not mistaken that model uses a gigabit ethernet chipset. There are problems with some switches (I am assuming he is using a switch) autonegotiating with the ethernet chip on that Dell. While I've only seen these systems as Windows servers so far, the fix should be the same for FreeBSD, and that is to hard-code the port to 100BaseT half duplex. If that does not help, try substituting a more modern switch.

I'm sure you'll get a lot of help on this forum, but I suggest you split your problem up. Focus first on your server: How is it configured? Have you tested the performance of file IO locally? Are you swapping? Is anything else running besides the samba processes and calyx? Have you considered 6.0 for file performance reasons? Test the speed of your database searches locally before you worry about testing them over the network. Next the network: What hardware are you using? How is it configured? Are all clients connecting at maximum speed (typically 100mbps full duplex)? How fast is a single client file transfer (without samba and without other connections to the server? Is the network overloaded with other traffic? Since you say some clients, what is different? Test using IP addresses not names. Next naming: If the low level network is fine, then slow connect time is usually a name resolution problem. What is different on the slow clients? Is samba your WINS server? Figure out how each client is resolving names and in particular resolving the name of the server. Do you have any master browser conflicts? Test each client's connect time with a non-samba program, e.g. ssh. Note ping sometimes gives you a clue if the first packet sent using a name and not an IP address times out. Check carefully that your default domain name suffixes are correct. Samba: It should be pretty fast out of the box if the above is working fine. I've never noticed any performance degradation using samba as a WINS server, and I recommend it. Turn it on in smb.conf and be sure to set it so that it wins any master browser elections. If you still think Win2003 is outperforming samba on comparable hardware, then you'll need to gather a lot more data. Calyx: I don't know anything about it. If local queries run fast (step 1), and the above are fast, then it would seem to me that its client has a problem. If it is only a client database (like QuickBooks or Access) that uses samba for its files, then you are into another class of performance problems and the calyx experts need to help you. (For example, the performance tunings for QuickBooks are much different that those for Access.) I'd recommend splitting your question to this forum up into separate questions formulating each so that it is interesting in its own right and includes what you have learned in previous steps.
