Maybe I'm mistaken, but I think you can make your code faster as well...
get '/' = sub {
my $self = shift;
my $sth = $self-db-prepare('SELECT id, content FROM updates');
my %data;
$sth-execute;
while (my $r = $sth-fetchrow_arrayref) {
$data{$r-[0]} = $r-[1];
}
$self-render('invalid', %data);
};
1) fetchrow_arrayref() is faster than fetchrow_hashref(). And it works,
since you know the position of the columns because of the modified SELECT
statement.
2) You only loop once. Which is at least twice as fast.
3) You never call stash, but pass the %data directly on to render() instead.
A completely different thing is that the code doesn't do any error
checking. I would suggest using https://metacpan.org/pod/DBI#RaiseError

Dunno, thousands of method calls is generally not a smart thing to do,
optimizing for it seems wrong.
I am trying a few things that appear to improver overall performance
though, more proposals along those lines would be welcome.
