...faster ?

faster than molasses in January? Yes. (In the northern hemisphere.)

faster than calling glBegin/glVertex/glEnd? Maybe -- it depends
on the implementation and exactly what you are doing.

How many polygons are in this hemisphere ? :)

No, well, I meant.... are *Interleaved* Vertex Arrays faster than
standard Vertex Arrays, where I declare separate arrays for
vertices, colors, texcoords, etc.etc.

Well, I've got 3 just in this room of my house, multiply by 5 rooms per house,
multiply by the number of houses in the hemisphere... :-)

They might be. They might be slower. I can come up with a few reasons
why a hypothetical implemenation would have fast interleaved array
performance. I can also come up with a few reasons why another
hypothetical implementation would have slower interleaved array
performance.

It also depends on what portion of the geometry is clipped out or
culled.
