But still I have some reservations,... here i'm quating from one of my
mate which I just consulted.
"diskd is sysV IPC based and scales based on IPC message passing
efficiency, aufs is threads based and scales based on pthread locking
efficiency & system scheduling overhad the overhead of both is ~ the same.
and they have been profiled to within an inch of each other in linux,
with no /clear/ winner"
