Have you timed it server side? I wouldn't be surprised if at least
half of that is browser-rendering time.
I've tried a quick script that prints a form with 1200 checkboxes, and
it typically takes about 4.2 seconds with TT, and 4.8 seconds with
I would hope most servers have more cpu and ram than the old laptop I'm running.

I'm guessing your template is calling form.render.force_error_message ?
HTML::FormFu::Render::Form doesn't actually have a
force_error_mesage() method, so it needs to fallback to the hash-key.
In your Template/Alloy.pm at the quoted line number, add a "warn $@"
immediately before the line that reads:
die $@ if ref $@ || $@ !~ /Can\'t locate object method "\Q$name\E" via
That should reveal what's going wrong.
$@ should contain the "Can't locate..." string, so it knows to
fallback to trying a hash-key value.

1200 checkboxes does sound a lot!
Just for that element, you could try inlining some of the included
templates, and set the element's filename() to the new file.
