A bit more info might be helpful, including:

1. The size of POST request you are making
2. The physical network layout (localhost connection versus
intercontinental)
3. Some numbers you are trying to reconcile

As Tim points out, the TCP negotiation and part of the HTTP conversation
will occur 100% before the AccessValve timing starts, so HttpClient's
total-time-to-send will likely include that overhead.

Give us some time discrepancies and maybe we can comment.
