public static void writeString(final ByteBuf buffer, final String val) {
   int length = val.length();

   buffer.writeInt(length);

   if (length < 9) {
      // If very small it's more performant to store char by char
      writeAsShorts(buffer, val);
   } else if (length < 0xfff) {
      // Store as UTF - this is quicker than char by char for most strings
      saveUTF(buffer, val);
   } else {
      // Store as SimpleString, since can't store utf > 0xffff in length
      SimpleString.writeSimpleString(buffer, new SimpleString(val));
   }
