That's what CURL does since mid-2013, yet there were at least 3 issues
reporting slow uploads on Windows since then.

Could you please run an experiment of your own? If you decide to use
my code, you need to pick a different URL, I used a server from
private network that you will not have access to. I'm very interested
in your findings.
