It is said that bumblebee is used to make Nvidia Optimus work on linux. The wikipedia Optimus description says that

The switching is designed to be completely seamless and to happen "behind the scenes".

However, after installing bumblebee, the recommended test seems to be to compare the operation of glxspheres with the operation of optirun glxspheres. The latter is faster than the former. If the switching is supposed to be seamless, why do we optirun to speed up graphics? Shouldn't it be automatic?

I believe you're taking it out of context, it is seamless in Windows. –  Uri Herrera Nov 2 '12 at 4:47
