Still slower than bind:
{ my $t0 = [ gettimeofday ];
my $n = 0;
my $rows = $dbh->selectall_arrayref ($sql, { Slice => {} });
foreach my $row (@$rows) {
$n++;
}
printf STDERR "slice: %9.2f recs/sec\n", $n / tv_interval ($t0);
}
{ my $t0 = [ gettimeofday ];
my ($n, %rec) = (0);
my $sth = $dbh->prepare ($sql);
$sth->execute;
$sth->bind_columns (\@rec{@{$sth->{NAME_lc}}});
while ($sth->fetch) {
$n++;
}
printf STDERR "bind: %9.2f recs/sec\n", $n / tv_interval ($t0);
}
=>
with postgres on other server:
slice: 23842.81 recs/sec
bind: 27994.01 recs/sec
with postgres on local server:
slice: 214963.65 recs/sec
bind: 505370.38 recs/sec
YMMV
Enjoy, Have FUN! H.Merijn

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
