The application looks fine, and you said it works fine with linux. I don't know whether this will help you, but I would have compared - 1) The mtu values of the windows with the linux system. 2) checked the tcp receive mem size in windows and Linux.

A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
