Adam, Thanks for the reply. For #2, you said that the data is sent using completion port thread. Is this thread part of the .net thread pool ? or is it custom implementation ? (Note: .net thread pool has 2 kinds of threads: worker or completion port/io).

The data is written on an IO completion port (or read when doing BeginRead), your callback is activated on a thread pool thread.
