I found a nice article here.
Basically, you want large sets not in an arrayref, but as a hash, since it's more clear what column holds the data.
e.g.
# tested this on live data, this is twice as fast as fetchrow_hashref,
+ and has the same advantage..
# example taken from the link above.
my @fields = (qw(emp_id first_name monthly_payment));
$sth->execute;
my %rec =();
$sth->bind_columns(map {\$rec{$_}} @fields);
print "$rec{emp_id}\t",
"$rec{first_name}\t",
"$rec{monthly_payment}\n"
while $sth->fetchrow_arrayref;
*Update*
Hmm, Funny indeed, anyway, i still consider this as a valuable way to speed up the DBI. :-)

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).
