I suggest you try removing the form, but leave in the DBIx::Class find()
I suspect the DBIC class setup is taking up most of that time.
I think the latest Class::C3::XS should help.

To test FormFu, run:
    $ prove -l t/04basic.t
t/04basic....ok
All tests successful.
Files=1, Tests=7,  1 wallclock secs ( 1.06 cusr +  0.05 csys =  1.11 CPU)

This test builds and renders 3 separate forms.
This will give you a baseline for the basic FormFu functionality.

Sorry, I haven't had a chance to look at your app yet.
I think it's a case of encoding is *still* broken - from your
description, there's definitely something wrong.
