It also depends on whether you drop file-backed pages or not, etc.

The hybernation image is compressed and stored as single file or inside
the swap partition. Accessing that can be a LOT faster than the
accesses during doing boot (unless SSDs are involved).
That said, I don't trust hybernation. Your data is much safer in the
long run if you restrain yourself to suspend-to-RAM and shutdowns.
