Dunno. We really haven't done a lot with this; it's not even in our stress test tool. Compaction is roughly 2x as fast with bytestype as asciitype, and scanning is vaguely similar to that. > I would be interested to know the types of optimizations you are planning.

Right now scanning does one pass to get the keys, then another to get the slices, so merging those is the really obvious one. -Jonathan
