Does Yeast Nutrient Typically Speed Fermentation?

I am about to use a third generation slurry for a lager I will brew this week. I need this to be through fermenting and diacetyl rest in fewer than ten days. I thought adding a little yeast nutrient to the wort may help things happen a little faster -- that and turning the fermentation temperature up a couple of degrees.

My lagers are usually ready for their rests in 7-10 days after pitching. Does anyone with experience with yeast nutrient think adding it would shave off a day or two?

Thanks.

It might, it might not. I'd venture to say it mostly depends on the state of your yeast before you pitch. Have heathy active yeast, it may or may not make a difference if you add it or not. It probably helps an underpitched, slightly inactive yeast take hold of fermentation, but in the end, your beer will be better off with a longer fermentation anyway. Wake up your yeast in a starter, regardless.

why are you in such a hurry?

i dont think the nutrient will speed the fermentation. if anything i would think it would make fermentation easier on the yeast and making it more efficient resulting in less unwanted byproduct production.
