Thanks for adding this, it is very helpful. One question is left:

Which combination of cache/journal/nosync makes sense. For highest performance does it make sense to use all three, or might it better to just use cache+nosync, because journal causes extra disk writes (cache to overcome network latency and nosync to get better write performance on the server).

Which combinations of these three make sense?

Regards
