Share WebJun 15, 2011 · 1. As far as I know in some machines multiplication can need upto 16 to 32 machine cycle. So Yes, depending on the machine type, bitshift operators are faster than multiplication / division. However certain machine do have their math processor, which contains special instructions for multiplication/division.
