Hi Paolo, about "performance reasons" recently we spoken about this item in other thread:

[Qgis-developer] On the fly simplication of point layer

In order to render so big layers as LAS files are, there are two strategies, discard points on renderer side, or on featureiterator side by distance proximity.

I think interesting to continue this item.
