There is a memory issue with the WIP regarding points and pointclouds.
I extracted a set of meshes from a complex file, deleted the objects and joined the meshes.
The result was a 1.8 M polygon mesh and selecting the object is fast in V5 but in V6 it takes a few seconds.
Extracting the vertice points is quite fast in V5 (ExtractPT) and it is possible to quickly transform it into a pointcloud. It used 3GB ram. In V6 this was not possible as the memory usage exceeded 8GB.
Join two pointclouds into one.
Split a pointcloud into parts, either split by surface, by line, or by dragging a rectangle.
