Open databases exclusive and read-only if for fastest single-user network performance

If you open an .MDB file both exclusive and read-only, this will avoid the creation of the .LDB file and will also stop any locks from being placed on the database. Over a network, this will result in less network traffic and speed up access because no file locks are being placed. On a local hard disk, the differences are likely to be negligible. Similarly it may be hard to measure the differences on a lightly loaded network.
