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.
