I apologize for resurrecting an older thread, but I'm having the same problem on Windows 7 x64. However, if I upload on my Mac Mini, it is infinitely faster. Seems like it might be a Windows-specific bug. Also, I'm in Portugal.
Could someone please have a look into this?
Thank you kindly for your time.
If you're only seeing the issue on Windows, my best guess is an Anti-virus software throttling the rate at which butler can work, either when reading files from disk, diffing them in-memory, or sending them over the network (the disk/network ones being the more likely).
Are you running any AV software besides the built-in Windows stuff?
