I don't really understand what those 10 MB are.
on both the receiver and sender pc's.. doing this the cwnd at the sender grows till X/RTT otherwise it is limited by the receiver
How is cwnd measured ? Besides those settings, were there any tcp buffers set manually (via setsockopt()) ? Could you give me more details about the machines' configuration as well as the underlying network ?
