For a transaction processing database workload, it's generally good practice to run with "zfs set primarycache=metadata", which means that ZFS won't attempt to cache anything except metadata. This might have reduced the 15% cache overhead the author observed. I'll be interested to read the future work on using larger page sizes. Conventional wisdom would hold that it was a bad idea (at least, for a write-heavy workload) because of the write-amplification that it produces, but it sets me wondering to what extent ZIL-offloading could mitigate that. Then again, there's really no point in putting the ZIL on ephemeral storage.
