Probably within reason.
A few thoughts on speeding it up:
The tabbed docks take a little longer to load than the standard docks, so sticking just to standard docks will speed it up a little if you like. Not a huge deal though. (Don't forget to save your theme before you start deleting docks if you want to play with it.)
Getting rid of the weather docklet might speed it up some, not sure, would cut out the communication to the weather site at boot.
Loading it up manually after boot cuts down on the boot competition if clicking to load it afterwards doesn't bother you.
Normally I boot in slightly less than a minute.
Only in my dreams, only in my dreams - I'm not even going to tell you how long it takes this crate to fire up
