> SocketIoProcessor always allocates a buffer whose size is same with the socket receive buffer size, which is often very big (e.g. 40kb).  Because the buffer is allocated for every read operation, the buffer allocation can often be a bottleneck because most applications don't fill the socket receive buffer that much.
> One solution is to dynamically adjust the size of the read buffer instead of using the socket receive buffer size value.
