Hi, at one of customer's machines, I've spotted an issue that sync(1) called after writing a single huge file has been achieving rather low throughput. After debugging this with blktrace, I've found that the culprit was in flusher thread racing with page writeout happening from XFS sync code. The patches below helped that case. Although they are not a complete solution, I belive they are useful anyway so please consider merging them...
