I see. What's the performance of curl on the same connection?
I took a quick look at your code; noticed that you use
CURLOPT_READDATA without CURLOPT_READFUNCTION; this is not exactly a
reliable combination under Windows where mixing compilers and standard
libraries is pretty common. It might be responsible for the timeouts
you saw.
