Yes, no real way around it, sometimes manually bounding can give a little speed
boost, but not much.  The original object can be broken into smaller pieces as
well and manually bound, but this can be difficult to implement very well, at
least for a significant speed improvement.

But, removing a single blob entity consisting of several blobs is considerably
faster than removing the equivalent in spheres, if the objects can be made of
blobs (using the basic formula in the docs, you can mathematically get the
blobs the same size as spheres of a specific radius)

A mesh would likely be far quicker (at rendering) and likely far more versatile.
