Neither looseness or tightness in the cable, whose proper length (tension) is set according to what gives correct trim the same as the rear.
Front shifting is always noisier for a few reasons; because it's a bigger jump, because it's on the power side of the chain loop as opposed to the return side for the RD (this is why you must ease up on pedal pressure to shift), and because rather than pulleys the FD only has a metal plat that the chain rubs against during the shift.
If the effort seems high, try it with little or no pedal pressure, and if it's still high look for a source of binding or friction along the cable run.
Also be aware that the return spring on the FD is often stiffer than that of the RD, so that alone might account for the difference.
