[Catalyst] Maybe there is a need for some speedups of 'config' method ?

[Oleg Pronin]

1% here and 1% there. You won't detect any place that takes longer. All of
load is 1%+1%+....
Don't you agree ? Plus a number of plugins calls ->config on startup which
slow downs startup as well)

P.S.
  I use many actions that take params from config in runtime, for example
  sub pay_for_vip : Private {
       ...
       my $price =3D $c->cfg->{vip}{price};
  }

And in my deepest opinion we should now spend CPU time anywhere even if it
is not a concern.

Thanks anyway)

This is convenient + good HUP support for deamon servers (that use catalyst
as well) - all you need to do is to refresh config on HUP.
