We've had this discussion here before and despite what the user guide says about holding the switch to turn your Kindle off, it does actually just seem to put it into a sleep mode with the display turned off.

The Kindle wakes instantly from both sleep mode and from when it's supposedly switched off, so it's clearly not really fully switched off then is it? All sorts of things take a while to properly turn on (mp3 player, games console, computer etc), so it makes sense the Kindle would be the same.

There is one a difference between the sleep mode with the screensaver on and sleep mode with the blank screen. If you leave the Wi-Fi on and put the screensaver on, it will download books that you send to it while sleeping. When you switch it back on, the books are there waiting.

If you leave the Wi-Fi on and put it in sleep mode with the screen off, it takes a few seconds when you first turn it back on for the books to appear, but not as long as you'd expect it to take if it was going through the process of reconnecting the Wi-Fi signal and connecting to Amazon to download.
