Meaning an entity model with 10, maybe 20 entities or more, lots of associations, and with data involving big entity graphs (because long chains of associations, cycles, ...)

This would be useful for multiple reasons:

• To keep bootstrap performance in check (be sure that we don't have some code running in O(e^n))
• To compare bootstrap performance between Search 5 and 6
• To compare indexing performance between Search 5 and 6, in particular in mappings with a lot of @IndexedEmbeddeds (which means a lot of reindexing of other entities when one entity change) and a lot of non-indexed properties (which should not trigger reindexing when they change)
