I was particularly surprised by the SOLR-64 numbers. What makes it's
response so huge (and thus slow) to return the entire tree of facet
counts?

I'm sure I'm only scratching the service with the currently
implementations of both SOLR-64 and SOLR-792. Alternative
approaches are welcome! As I said on the wiki page, there won't be
any single method that works in all cases - it will depend on how
the hierarchical counts are needed - as an entire tree? (not likely
in large taxonomic cases!) How are level pruned counts needed?
Implementation-wise, seems like payloads could be be useful for some
use cases.
What are the use cases?
What types and sizes of hierarchies are folks dealing with out there
in the real world?
