No. The transferTo method calls WritableByteChannel.write(..) multiple
times. For example, transferToArbitraryChannel(..) create a 8KB buffer and
call WritableByteChannel.write(..) every 8KB. We must send small packets in
Streaming.
```
//sun.nio.ch.FileChannelImpl
private long transferToArbitraryChannel(long var1, int var3,
WritableByteChannel var4) throws IOException {
int var5 = Math.min(var3, 8192);
ByteBuffer var6 = Util.getTemporaryDirectBuffer(var5);
```
var6 above is the 8KB buffer.
