@benlwalker - as part of this topic, could you talk about any of the stacked bdev improvements you have been prototyping? I feel like this is an important consideration for this topic - i.e. does accepting a 4-5% degradation based on random performance impacts enable a much bigger improvement for stacked bdevs or other optimizations?
