### Performance compared with the original Arduino environment
481+
482+
Benchmarking the original Arduino examples from Arduino 1.0.5. The simple
483+
Blinky cmopiles to 57 bytes of code, the total binary including the sduino
484+
libraries is 1868 Bytes (0x74c).
485+
486+
So far, wiring_analog depends on wiring_digital, even when analogWrite is not
487+
used. This could be solved by compiling the sduino functions separately into
488+
a library.
