It changes if it's a first boot off a reboot or second time, when memory has much of the application cached.
First time, it takes like maybe 2 to 3 seconds for Safari, maybe less than a second on second time. About same or 1 seconds slower for iWork I think. Didn't time precisely though, but just how I felt. SSD should do them all faster. But only for first boot, second time seems to do just about same, since they are cached on memory.
