#4773 closed Enhancement (invalid)

Use hard links instead of copying data when source and dest are on same filesystem

Description

When a torrent is moved from incomplete-dir to download-dir or when a user changes the data location of a torrent, the data is copied, which causes unnecessary i/o if the source and destination are on the same filesystem. Especially since there is no separate thread for i/o, this can cause transmission to block for a while. Hard linking the data files would be much more efficient when possible.

Hm, iirc we try rename() first before actually copying the file, so if we're doing same-filesystem movement it shouldn't be copying right now. Mechanic, could you double-check this request?

You are correct, my bad.
