Thanks Michael, I´m trying to send it again, this time as zip file.
About the poor performance, I'm measuring time only after receiving the 100 server response, in the second step of the handshaking process. In the C++ version I have, I don´t know if it does or not the 100 handshaking - I don't have the code. Anyway, it´s much faster, and I don´t believe it´s because it´s implemented in java. The http version has similar times in the java and C++ version. Can you point me a similar jsse implementation? What about the constant times? It´s the weird thing. It takes the same time in the first part of the negotiation, when it send the 100 header, and in the second part - actually when the request is processed in the server. Any explanations?

Jeff, Oleg do you have any idea how we can get this fixed? I'm guessing the poor performance with SSL is due to the "Expect: 100-continue" header. Try calling setUseExpectHeader(false) on the post method. I would also suggest using the latest code from CVS or a nightly build.
