Not parse faster. The rendering can benefit from the internal bounding 
and hierarchy mechanism of the blob.

In my case, it was done using a recursive macro. The parsing time was a 
little over 10 minutes, the bounding time using +bm2 about 2 to 3 minutes.

Parsing of a sequential cluster of 75000 small spheres should not take 
more than about a minute. The bounding time only a few seconds.
