Many database support some form of bulk insert, like
Sybase's bcp utility (and corresponding library).
That should be the fastest way of doing multiple inserts.
Your database might not support doing a bulk insert into
a non-empty table - in that case, insert the stuff into
a temporary table, and use a stored procedure to move the
stuff from the temporary table into the final table.
Also, if you have indices on the table, drop the indices,
do the insert, and create the indices again. Dropping and
recreating insert triggers could also be a huge gain, but
you have to make sure it's safe to drop the trigger.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
