I don't think that's the problem.

It looks like the server isn't handling the 100-continue properly. curl
switches to using 100-continue when the post is larger than a few KB, so
that's probably the difference you're seeing. Try disabling this by
switching to HTTP 1.0 mode with the -0 switch or disabling the Expect:
header with -H Expect:
