use make slice to store objects to improve efficiency

Signed-off-by: allencloud <allen.sun@daocloud.io>



**What this PR does / why we need it**:

we we know the slice length in advance, I think we had better use make to create the specified length of slice. This will improve some kind of performance. Since if we create a slice with []type{}, we did not know how much space runtime should reserve, since slice implementation should be continuous in memory. While when we make a slice with specified length, runtime would reserve a continuous memory space which will not result in slice movement in case of current space is not enough.
