Volume select on animated loft slowing machine

Hi
Reposting this to try and get a response.
Have a volume select particle emission on a lofted object with progressive morph animations (controlled via expression controllers) and its slowing the machine.
Anyone know why and suggested fix?
Other PFlow emitters are working fine on more simple (simple transforms) animated objects.

cant really tell whats going on without a file.

Try to pointcache your mesh and then disabling all modifiers below the point cache. See if that helps speed it up.

Thanks Nickolay. Good idea to "bake" the mesh. I was wondering how to do that.
I have applied the point cache.
It only records when i have all the modifiers below turned off.
If i have them on it gives message "point count changed while recording"
I have some slice modifiers on there that could be changed the point count.
I'll post the file too.

Ok since topology is changing the pointcache will not work.

I would try to use the volume select to inverse your selection and apply a delete mesh modifier on top. That way leaving only the birth areas for pflow and reducing polygon count.

See if that speeds it up!
