If you look at the start time up the top it started at 18:00 and finished the next morning at 8.55 over 14 hrs which
seems very poor perfomance??? But if you look at the robocopy totals the total time is 2:32 ??? The speed is 22595743 bytes
a second (172 megabits a second)  which seems to me a very good performance. If it is taking 2:32 what is doing for the other
time??

Why have you got 295567 skipped files? It´s possible that files are in use? the time displayed is the effective time of copy, no waiting time because robocopy locked files or whatever

it's the "extra" time of 2:19:44 where is is checking if a file has to be copied over, actually, comparing the flags/times of the local and remote file

Is skipped files not just files that have no changes so do not need to be copied ???

So if i am understanding this extra time this is the scan of the files comparison is taking 2:19 and then
the copy over the network is taking all the other time??

What this tells you is that it went through 15502 Directories--all but three were already there so it only copied 3 new directories. It read through and compared 295685 files, files on the source and compared them to what was on the destination--based on that comparison it only copied 118 "new" files (new or changed)--the time it took to copy those "new" files and directories took 7:58--the remaining time of 2:19:44 was used to compare files.

This does not compute with the notes above and so cannot explain this. Can you re-run it again for me and let me know these times again--it should only be showing around 2 hours and 20 minutes elapsed and not 8.
