hey guys, just wondering if this is on the radar, since it sounds like it can help with write performance?
benbjohnson commentedon Feb 2, 2015
I haven't made any progress on this yet. It hasn't been much of a priority because I'm not sure how much it'll actually help performance. The main performance issue with random writes is that they amplify writes a ton. You likely end up getting throttled by disk write speed and not syscall invocation time.
