Live Effect slowing down dramatically with bigger art tree's.

Fellow Developers,

I making a plugin with some live effects in it.

What I notice in general, even with Ai built in live effects such as for example transform:

When I apply an effect to a layer, the time to get in the EffectGo method/message dramaticaly increases when the art tree gets bigger in that layer. 250+ art objects is allready lagging the system and 500 sometimes allready tends to timeout and just go in quickpreview line mode. 

The question : Is there a way to just make it EffectGo and not do the 'gathering' thing?

Only passing the ArtHandle of the Layer or object where the filter acts uppon?

Rather then the whole shabang with a big 'message->art' group containing copies of all art and extra art with more art... all the time? (I'm guessing creating this one is slowing down the system dramaticaly)

Can it be disabled or tweaked so it fires on edits but lightweight without the bloat?

Any hint is welcome...
