The Optimistic File System (OptFS) is a Linux ext4 variant that implements Optimistic Crash Consistency, a new approach to crash consistency in journaling file systems. OptFS improves performance for many workloads, sometimes by an order of magnitude. OptFS provides strong consistency, equivalent to data journaling mode of ext4.
