Andy Seaborne commented on JENA-729:
------------------------------------
The large WERE clause (10k triples in the example) causes a 10k long chain of
triple matches.
An improvement would be special case exact matching (i.e grounded triples) and
convert to a block of adjacent grounded triples to do a fast "contains" check.
