Description
investigate how async close RPC can improve small file performance for cases like tar -xf
we used to have this in the past, but performance impact was rather negative even with a single thread. it makes sense to evaluate the idea again with multislot feature.
ideally, open/close(no OST objects) rate should be very close to mknod rate
