Felix, According to my tests there is difference in performance between usual named buckets (test, test01, test02), uuid-named buckets (like '7c9e4a81-df86-4c9d-a681-3a570de109db') or just date ('2016-09-20-16h'). Getting ~3x more upload performance (220 uploads\s vs 650 uploads\s) with SSD-backed indexes or 'blind buckets' feature enabled.
