I don't believe so and I don't think it's really a memory problem. Perhaps could you describe your problem a little more detailed? Frankly, I don't really see an issue.
I noticed it also. Rebooting the system, waiting for the menu button to appear. This might take a few seconds aftre the system is ready booting. I'm really curious why this happens.

It's a problem because I can open home folder via the shortcut on the desktop and open the terminal at the desktop via right-click. So something about the menu is making take longer to load.
I think the menu is probably just a plugin. It would load after the desktop is loaded. While annoying, it isn't really a bug. Perhaps the time can be cut down in an updated version (which would come in an update pack), but I do not believe this is a user-specific error.
Perhaps hibernate your system instead of a full shutdown? That would dramatically shorten your boot time.
