Defer writes give the biggest speed boost and unfortunately the least safety (crash).
I have to say it happens rarely so I just use defer/lazy write,
But perhaps there is some hybrid possibility.
FC monitors IO activity.
High I/O activity: Increase defer write time (configure a max)
Low I/O activity: Decrease defer write time (configure a min)
Seems a good thing to do but all that extra logic takes CPU cycles.,,,,
