Hi!I have the next problem:We have a 12 Mibt/s WAN. The delay is 40ms. There are out-of-order packets, from 10 packet come back 3 in incorrect order. Because of this, between two Windows (Windows XP, 2000 Professional, 2000 Server, or 2003 Server) is the maximum bandwidth 800kbit/s over TCP. It doesnt matter, wich protocoll is in application layer (SMB, FTP, SSH,). In test environment is the same case, if i set out-of-order packets over the test connection (with random delay). Between two Linux isnt any problem, they use the maximum available bandwith. And the most interesting thing: If the sender is Linux and the reciever is Windows, isnt any problem. But if the sender is a Windows machine, it sends only with 800kbit/s. (Over the WAN, and in the test network too.) If i set the "TcpMaxDupAcks" TCP/IP parameter on the sender, the bandwidth will be 1 1,1 Mbit/s, but it is just a little result.Can somebody help me? Thank!
