Sounds great. What storage configuration did you use (single spinning disk, SSD, storage array) and are these numbers for parallel I/O or sequential I/O? What changed since Minchan worked on this? I remember he wasn't satisfied that this was a clear win. Your numbers are strong so either you fixed something important or you are looking at different benchmark configurations.
