Possible negative impact of setting socket.send.buffer.bytes to a high value

Question

So I was looking to increase the property "socket.send.buffer.bytes" to a higher value than the default of 100kb it comes with. I needed to do the same to optimise our mirrormaker replication process which is in another data center. I was wondering if there can be any negative impact of doing the same on the normal producer / consumers in the main data center. Also could this lead to me being able to form a lower number of connections if the memory is allocated per socket for the buffer ?
