Reading the comp.protocols.smb newsgroup sometimes has its benefits :-). Someone just posted there that they improved the speed of their Win9x systems by a factor of 15 against a Samba server by applying the patch to *all* versions of Win9x (*NOT* NT) described in Microsoft knowledgebase article : Q236926 -found at : http://support.microsoft.com/support/kb/articles/q236/9/26.asp?LNG=ENG&SA=ALLKB Apparently Win9x (all versions) has a bug in the TCP RTT calculations that can cause premature retransmissions of packets. Now the article claims this is only on high delay networks (satellite links etc.) so your millage may vary. There is also a patch for NT4 SP5 and below (the fix was rolled into NT4 SP6). Articls - Q232512 refers to the NT fix (there is a link to this from the web page above). If people on this list having performance problems could try this fix out and report back I'd really appreciate it. If it turns out to be beneficial I'll add a link to the main Samba web page and add it to the Samba docs for the next release. Cheers, Jeremy Allison, Samba Team. -- -------------------------------------------------------- Buying an operating system without source is like buying a self-assembly Space Shuttle with no instructions. --------------------------------------------------------
