Curl presents an error for sites that do not support resuming, I see it
when I forget to add the cookie headers, and Firefox is able to resume
transfers where it left off.
When I was monitoring the end of one I let complete yesterday, curl
reported that it was downloading at about 9MB/s (verified using task
manager) for about 5 - 10 minutes, but the files were all 100% of their
expected size and did not change size during that time, the end of which
curl successfully completed.
My guess is that curl is working as expected and that my expectations are
flawed. Perhaps it is preallocating the space in the files and then
filling it in, storing it in memory or a temp file somewhere before writing
it to disk, or I'm not monitoring it closely enough?
