Beginning with Domino 8.5 there are many more files installed under 'domino' directory of the data directory. Some of contents, like 'domino/js', have been blocked from access via Domino API calls. This means that scanning the data directory takes much less time than it would have if the 'domino/js' subdirectory had not been blocked. However, other subdirectories, like 'domino/html', are still included in the file scan. An example of such a scan is when the Domino Administrator client enumerates server databases via its 'Files' control.
The NOTES.INI option ADMIN_CLIENT_SKIP_DOMINO=1 will disable enumeration of every single file under the 'domino' directory.
Default: When ADMIN_CLIENT_SKIP_DOMINO is absent or set to '0', the default behavior is to scan many (not all) of the files under the 'domino' subdirectory.
Set ADMIN_CLIENT_SKIP_DOMINO=1 in the server NOTES.INI to improve internal server performance and reduce Domino Administrator 'Files' control initialization time.
