You don't mention it, but I assume you are using DBI/pg. You are sure you
are setting up you
insert qyery handlers once and then reuse them? >s setting up a query
handler takes a lot of time.
ie
my $dbh=DBI->connect(dbi:Pg ...);
my $insh = $dbh->prepare("Insert into table values (?,?,?)";
foreach ($excelrow){
parse;
$insh->execute($data1,$data2,$data3);
}
I have written a few script of that kind my self, and I was really surprised
how much it mattered when I managed to move a $dbi->prepare out of the
insert loop.
