I ran across a weird (to me) issue today that really slows down a script im running. (in fact it never finishes) The script is a cgi-script. Here is the part that is slowing down, i know this because i can eliminate the slow down, but im wondering why it slowed down in the first place. 
...
    foreach my $field (sort @$field_order) {
        print "\t<TR>\n";
        print "\t\t<TH ALIGN=RIGHT>$field :</TH>\n";
        for my $i (0 .. $num_recs) {
            print "\t\t<TD ALIGN=LEFT>$records->[$i]->{$field}</TD>\n"
+;

        }

        print "\t</TR>\n";
    }

$records is an array of hashrefs of strings, nothing special. The inne loop contains only the one print statement, and that is where the slowdown occurs. If i add the following line, like so: 
...
    # heres the new line of code
    $records->[$i]->{$field} .= "";

    print "\t\t<TD ALIGN=LEFT>$records->[$i]->{$field}</TD>\n";
...

then this script runs fast.
I have also tried checking the lengths of each value : 
   length($records->[$i]->{$field})

and they all are reasonable. I have also taken refs to various parts of this data structure, and looked at it with Data::Dumper, and nothing unusual appears.

So, i am completely perplexed! - but i have found a workaround.
Any insight would be great. If you need more info, let me know.

A co-worker is trying to get mod_perl to work, so that may be it??
