Doing transfers over the internet is a whole other story than doing it in a LAN. I think you are addressing 2 different issues here. Optimizing for very high bandwidth (over 100MBit/s) might need some additional work on the internals of curl which are out of scope of the issue you described. I'm very interested if the speed-problem you described initially when doing cross country transfers over the internet is solved by the patch you wrote. By solved I mean getting the same or better performance than FileZilla or similar tools. If the problem is not solved I can't really imagine what the problem is, because the Windows TCP-Stack should increase the SO_SNBUF itself as necessary. That's why the manual adjustment of SO_SNDBUF should only have a very minor effect.
