Pedro,
I faced the same problem as you did.
The solution for me was to disable the "Expect: 100-continue"
header with

---
 m_headerlist = curl_slist_append(m_headerlist, "Expect:");
---
Now there's no delay between the header and the data-part anymore.
Comments in the sourcecode state that "Expect: 100-continue" is
intended to speedup posts, but at least in my case it did the exact
opposite.
