Long Exposures and noise reduction in camera or not?

Exposures that are loooong, say 2 min. or more. Should noise reduction be set on camera or not? If I under stand correctly the processing time for the exposure is as long as the exposure, so a 4 min. exposure would take 4 min. in camera to process? So if I where to turn it off and fix the noise with computer software after, this would be faster processing in camera and enable me to take faster pics, but is it the best way to go? Would I loose some" detail" of the pic while cleaning it up with software?.

You do loose a certain amount of detail when removing noise...I find if you don't under expose your long exposures The noise levels are reduced and exceptable..I usually use ISO 200...
