Sync was disabled on the main pool and then let to inherrit to everything else. The reason for disabled this in the first place was to fix bad NFS write performance (even with Zil on an X25e SSD it was under 1MB/s). I've also tried setting the logbias to throughput and latency but they both perform around the same level.
