Could be long ACL lists with many unique ACEs that need looked up on AD, and/or 
slow ADCs, and/or slow AV, and/or slow net:

for each file show the outputs of

	$ ls -dl $f
	$ getfacl $f
	$ icacls "`cygpath -m $f`"

and also attach as text, the output from strace on the cp command, as it will 
show the timing and delays e.g.

	$ strace -o cp-strace.log cp ...
