SyncToy 2.0 very slow with large files

[John]

Syncing large files (4GB video files) takes a very loooong time. SyncToy
appears to be creating a .tmp file of the file first (getting fairly quickly
up to 99% done with the file), but then it will sit there for perhaps 5-10
minutes at 99%.

Is this normal behavior? I don't recall 1.4 taking this kind of time. I
could do the copy manually in just a couple of minutes, but sometimes these
files go in total for 15-20 each.

John,

We'll look into this and see if we can reproduce the same behaviour you're
seeing. It definitely should not take much longer than it takes you to copy
the file using Windows Explorer.

Meanwhile, can you give us some details about your setup. What are you
syncing to/from (drive types - NTFS/FAT, local/network/usb, etc) and if
there's anything special about your setup?

Thanks for reporting this.
