I remember seeing that in the smb.conf documentation, but did not check to
see the results down the source path.
At this time I am unable to do any more heavy development and testing, but
will pass along this to the SAMBA-VMS list and see if anyone tries it.
I assume that since "case sensitive = no" is the default, that you really
meant "case sensitive = yes". As it is the default case that does the most
As a quick unscientific test, in a directory with only 37 files in it:
Case sensitive = Yes
Averages 32 seconds in several tests, no real variances seen.
Case sensitive = No
Averages 41 seconds in several tests, no real variances seen.
