I just tested this very easily, but unfortunately nothing was recorded in any of the /var/logs. The steps I used to replicate on a Lenovo P50 running Ubuntu Mate 16.04 LTS (fully updated as of 29 March 2017)
1) Open Caja 1.12.7 (also tested using Nautilus on Ubuntu 16.04 LTS)
2) Navigate to a folder that has 500 text files in it of very small size (5-10kb is sufficient)
3) Press F3 to open a new pane (or optionally open a new window, doesn't matter) and navigate to an empty folder on the same drive (or a different drive, doesn't matter)
4) Highlight most or all of the files in the source directory, and press CTRL-X (or edit > cut, doesn't matter)
5) Go to the destination pane, and press CTRL-V (or edit > paste, doesn't matter)
Sometimes, the cut/paste will happen nearly instantly as it should. Sometimes though, it will take a second or two to start, then spend between 1 and 20 minutes sitting there, copying the files one-by-one, very very very very very slowly. This issue is not reproducible using the 'cp' or 'mv' command line programs.
