Using database design compression
Use the advanced database property "Compress database design" to reduce the total cost of ownership of maintaining any IBM® Lotus® Notes® database by reducing the size of all design elements in the database. For the Notes client mail template (MAIL8.NTF), this setting is enabled by default and the design is compressed when the mail database is created.

This setting reduces design note overhead for IBM® Lotus® Domino® mail deployments.

Note To use this feature, the NSF must be ODS 48 or later. To upgrade a database to ODS 48, enter the following setting in your NOTES.INI file and use copy-style compacting on the database:


You can upgrade all the way to the current level of ODS (which provides more benefits than ODS 48) by entering:
This NOTES.INI setting affects only NSFs; it has no effect on DB2 enabled Notes databases. For more information on Domino on-disk structure (ODS), see the related topics.
