different yeasts work different ways. wit yeasts don't work quite as fast as hefeweizen yeast IME, for example. and if you aren't using a secondary, you should always leave in the primary longer.
i've had beer go from grain to glass in just 5 days, but it takes a big starter, arousal of the yeast, finings and/or filtering, and special care through the whole process.
trust me, your beer will be better if you let it wait a little longer. no sense in risking mucky beer just to save a few days time. and if it's not finished fermenting completely, you could stall fermentation and leave it sweet. not worth it IMO.
