I have a render cooking at the moment. at 404 s/p it's still fairly grainy but not at all to this degree. I also have a 2873% efficiency (whatever that means.. how can something be more than 100% efficient? L)

Until you get close to at least 1000 s/p, I'd say the render isn't done. Depending on a couple of things of course. 

But.. speed-wise I've often found Reality/Lux to be effectively faster than Firefly. Sure, you can have a render running for 10-20 hours... but OTOH if it really takes that long (and isn't incredibly large) there's something else wrong.

Here's mine at the moment, after approximately 2 hours. There's still grains in the shadowy areas (inside the shelves) but again, this render is far from done, even if Dawn is looknig nice and "grain free"
