security.

.TP
\fBdbpagesize \fR \fI<dbfile> <size>\fR
Specify the page size to use for a particular database file, in units
of 1024 bytes. The default for the
.B id2entry
file is 16, the default for
all other files is 4. The maximum that BerkeleyDB supports is 64. This
setting usually should not need to be changed, but if BerkeleyDB's
"db_stat -d" shows a large amount of overflow pages in use in a file,
setting a larger size may increase performance at the expense of
data integrity. This setting only takes effect when a database is
being newly created. See the Berkeley DB reference guide for more details.
.TP
.BI directory \ <directory>
Specify the directory where the BDB files containing this database and
associated indexes live.
