My own rule of thumb: if the defrag takes longer than an hour you need to do it more often. If it takes less than 10 minutes, defrag less often. You don't want to waste a lot of time in order to save a little time. Do the defrag during a quiet period, such as when you're away from your desk for a meeting, or after hours. In that way you don't waste any productive time.
