On OSDN file release system, uploaded files are mirrored to public mirror sites that are located around the world.
That means that until the mirroring of the file is completed, there will be a moment during which the file only exists on the master server. And during that period of time, the download speed could be extremely slow.
Mirroring to primary regions in the world usually completes within less than an hour, but the file which you uploaded was huge, so it could have take a few hours.
We just looked into it and found out that this file is already mirrored to all the mirror servers.
I suppose the download speed problem has been solved already.
