Catalyst automatically loads all the packages it finds under
MyApp/Controller, MyApp/Model and MyApp/View - at startup, not on
demand - so it knows what's available.
This is definitely a DBIC issue - not a FormFu issue.

Search the DBIC list archives for a thread with the title "Startup speed".
With the suggestions there, the OP managed to get his startup time
from 19s down to 2s.
