Originally named 'Speedup insert of buildroot_listing' - now it is done in simple cycle with hundreds/thousands of inserts - convert it to bulk insert.
I've gone through rest of hub code and found, that it is done in few more places. So I'm proposing BulkInsertProcessor to be used instead of InsertProcessor.
I was thinking about adding bulk option to InsertProcessor, but I've decided to make separate one with limited options, so less error-prone than IP with mixed type of data.
