Is the mult5 example an actual piece of code of your program?

Any multiplication where one multiplicand is a constant should be much faster with shifts and adds than with a loop. mult5, e.g. is: x+(x<<2)

Right, I do this in the assembly versions everywhere I multiply by a constant. mult5 is just an example.
