Yes, I understand!

I also don't know much about what they do. Basically they have several 
filebased databases opened, files like

BL6F.DAT
BL6F.IX (index, I assume)

and some .DIA files

That's small files, one whole subdir is maybe 20M per customer.

And the tasks are some processing in their software, which will result 
in much read/write in all the above files.

My assumption is that the locking behavior might influence the overall 
time needed here. That's why I excluded the DAT files via "veto oplock 
files", but that was years ago.

What's the general recommendation here, especially with Windows10 clients?
