Hi Andrea, your description of -f seems incorrect. cleanIndex() first removes from index all items which no longer exist in the database [1]. updateIndex() then iterates over all items in the DB and updates them in the index. In my test, as expected, -b was about 10% faster than -f, but I'd say it's still within the error margin.
