Acceptable and helpful in some situations, but be aware of data
integrity issues here if you crash - files may end up with wrong data in

Only possible if you have 8K or greater pages, and if you're on
x86/x86_64 etc you're limited to 4K.

noatime can make a difference.

-D is only useful/applicable on aged filesystems, it won't make any
difference on a new fs.

By and large, the defaults provide the best performance for "normal"
situations. That's why they're defaults. :)
