Copying via Nautilus much slower than via cp / pv

[amay82]

Binary package hint: gvfs

Steps to reproduce:
* Take a 50 GB virtual machine file and copy it via Nautilus from one disk to another
* First, the speed is about 70 MB/s as it should be and ETA is 12 minutes, but then it gets slower and slower and ETA increases
* It takes ~ 45 min then

Steps to get expected results:
* Copy via cp or pv (pipe viewer, just to see how fast and ETA) -> ETA is 12 min, speed is 70 MB/s but STAYS at this speed
* It takes 12 min

=> There is something in Nautilus / probably gvfs that takes aways 33 min. Because I do a backup of this machine always before starting to work on it, these 33 min are important for me.

Thank you for your bug report

upstream commented:

"Given that this is copying from one disk to another, it will be using the local
file implementation of gio which lives in glib, not gvfs. Moving to glib...

Anyway, does this still happen? That seems like pretty odd behavior."

is that still an issue?
