Maybe something external slows the starting process down? Do you load many otls or packages?

You could copy your preferences folder to another location and see if it starts faster with an empty userfolder.

// Is your Houdini located on an SSD? If it's on an old HDD or external Server that could also be the issue.

Just to be sure: Did you do the point deform with the equally scaled mesh versions? It sounds like there is an issue with an offset of these meshes which will be kept when using this node. You could also use the xyzdist function in VEX to be sure the meshes are snapped onto each other.

My bad, just tested it. One way is to use a group (point) and refere to this group in the attribpaint. If you want you could combine it with the visibility SOP to only see the object you wish to paint. I made a demo if it is interesting for you.
