write speeds without write-behind will be low for such small block sizes
because of the high context switch overhead incurred by fuse. A bigger block
size would help too. Please let us know the results with write-behind.
Writebehind showed almost no improvement at 4k block size, however moving
from 4k to 128k blocks made a major difference, jumping to 136 MB/s.
Anything else in my config that can speed things up? Should I be doing
anything more client side?
