> The BroadcastGroupImpl uses improper buffer handling to generate packages for broadcasting to a cluster. This results in sending 4096 byte packages (the size of the buffer) full of zero bytes with only about 250-300 bytes actual payload.
> This incurs needless weight on any underlying network equipment.
> This also may result in loss of service as large packages may be silently discarded.
