Hi, I have configured samba domain in our network of around 150 windows node, we are running 4 Samba server, Samba acts as PDC, member server, everything was running fine with windows 98, until we start upgrading our systems to windows xp, the network started becoming choke and problem of slow access arises everyday, I have checked with ethereal and the traffic generated by windows xp is almost thrice for the same work which windows 98 did. Please provide me some solution to overcome this problem. Regards, Honey

From my evaluation it is more like 3-5 times as much traffic for the same operations, but it makes a difference what you are measuring. For example, opening a directrory with 1000 or so file in Windows Explorer could cost up to 6 times more I/O traffic. Windows XP SP2 is a beast for traffic increase. The solution is revert to 98 - or else bit-the-bullet by migrating to Linux. - John T. -- John H Terpstra Samba-Team Member Phone: +1 (650) 580-8668 Author: The Official Samba-3 HOWTO & Reference Guide, ISBN: 0131453556 Samba-3 by Example, ISBN: 0131472216 Hardening Linux, ISBN: 0072254971 Other books in production.

I thought at it was purely due to how Windows 2k/XP handled their roaming profiles with all the data that moves back and forth during login/logout. Any thoughts on what the reason is for the increased i/o for similar operations?

Additionally, XP Pro in particular tried to the newer protocol extensions (supported only by Win 2003 Server and ADS) then backs-off. It does this in a number of ways before it eventually uses the NT4 style protocols. The overhead is significant - even with Win 20003 server! Furthermore, Win XP Pro negotiates Unicode support which is not supported by Win 9x. That too adds overhead. So, in summary, get used to it - Windows networking protocols are just noise on the wire! :-) - John T. -- John H Terpstra Samba-Team Member Phone: +1 (650) 580-8668 Author: The Official Samba-3 HOWTO & Reference Guide, ISBN: 0131453556 Samba-3 by Example, ISBN: 0131472216 Hardening Linux, ISBN: 0072254971 Other books in production.
