<h3>Berkeley DB Reference Guide: Access Methods</h3>
<p>
<h1 align=center>Hash table size (h_nelem)</h1>
<p>
The anticipated number of elements in the hash table can be specified as
part of the <a href="../../api_c/Db/open.html">db_open</a> call to open the database, specifically by
setting the <a href="../../api_c/DbInfo/info.html#h_nelem">h_nelem</a> element of the DB_INFO structure. If
not specified, or set too low, hash tables will expand gracefully as keys
are entered, although a slight performance degradation may be noticed.
