Implement a byte array pool for DequeueInternal

[akash14darshan]

Currently since we allocate a new byte array for every ByteBuffer dequeue we make, it may not be very efficient for high loaded server since it will increase gc by a lot.

Alternatively, a custom byte array pool can be implemented to handle this for performance reasons so that we do less allocations

Can you please describe the problem in more detail?
