FreeBSD: The Power to Serve
Softupdates
Three traditional file system mount types:
1. Asynchronous data and meta-data writes (Linux default). Very fast, but unsafe
2. Asynchronous data, synchronous meta-data writes (FreeBSD default). Slower,
but safer
3. Journaling. Can be very fast, but the code is complicated.
Softupdates is a mechanism for ordering meta-data writes
All the speed of (1), with the safety of (2)
Softupdates and journalling have different results on
different data sets
