On a more generic front, there's always libeatmydata which forcibly disables fsync. I've used it in the past for doing, eg, faster database restores.

Usually dramatically speeds up bringing up a replica. https://www.flamingspork.com/projects/libeatmydata/ https://www.flamingspork.com/projects/libeatmydata/
