reduce volume cloning time cost

Describe the solution you'd like in detail

currently every single volume cloning requires 5s, most of the time is wasting in waiting for next tick, maybe it's better using exponential seconds waiting, e.g. 0.5ms, 1s, 2s, 4s, 8s or simply set 0.5ms ticking, and only print logs every 5s?
