the following are true:

  <li> <p>All database content is stored in a single

       for search operations - minimizing the number of disk sectors that need
       to be visted when searching the database.

  <li> <p>The database file contains no (or as little as possible) free space.

<p>When optimizing the database as above, either the LSM_CONFIG_AUTOCHECKPOINT
parameter should be set to a non-zero value or lsm_checkpoint() should be
called periodically. Otherwise, no checkpoints will be performed, preventing
the library from reusing any space occupied by old segments even after their
content has been merged into the new segment. The result - a database file that
is optimized, except that it is up to twice as large as it otherwise would be.
