It -should- be faster, not slower - it uses (AFAIK) MRO::Compat to handle the
search order.

Are you using it with a DFS or C3 mro? Have you checked the MRO::Compat speeds?

A little basic investigation (and posting your benchmark code) would go a long
way here.

Plus Catalyst doesn't use C::A::G - maybe you wanted the DBIC list?
