Copy files over network - Dopus slower than Windows Explorer

Hello,

it is me again, I waited patiently and left you some time to work on this issue.
I tried again with DO 11 to see if things were getting better, but it seems to be still the same.

I repeated the test several times, so I give you the average times below.
For instance, if I copy from a network share (gigabit) to a SSD, it takes around 2 min using Windows Explorer.
Same copy in DO 11 takes always more than 2min 20s.

For my tests, I copied 2,82 GB (3 054 Fichiers, 374 Dossiers), with random files size (it has some big archives and small files also).

My DO copy buffer size is set to 4096.

Would it be possible to at least match the Windows default copy speed ?

Thanks guys
