It's actually quite a pleasurable pace
The reason (as I was told by someone who deals with the electronics on a ride) for the slow lift speeds is sometimes because of a shot controller, where the park doesn't have the money to replace it or they're too lazy to repair it. OR they're waiting for the off season.
A damaged controller can't send the power through the power lines it would normally be able to if it's fried, so it sends a lower current through to keep itself from burning out completely.
Another reason, which has been mentioned, is for blocking. I know more current controllers also are proportional wit the "throttle" so to speak, so it can adjust according to a trains position on the following block, to allow it to clear before the train reaches the top of the lift. No more 2 speed settings. Just nearly perfect timings, so dispatchers can dispatch a train faster.
Also, like on Goliath at SFMM, they and program (yes, they can be programmed- these ain't your cheap run of the mill controllers) them to slow a train once it's reached a certain point, triggered by a sensor in the track, to build suspense.
But lift hills that have been slow from the start (as in from the date the ride was opened) are either A. geared better to run on a less expensive lift motor system to haul the train up easier without excessive current going through the lift motor, or B. the controller can't handle the intended currents needed to pull the train up the lift fast.
From what the engineer was saying, Ultimate was a
lower budget ride, so they decided to go with a higher geared lift motor which cost them less on the rides total materials price.
-or so I've been told. I am fairly avid with the nuts and bolts of things, such as lift motors, speed controllers and gearing and the likes, so I can back up his statements a bit
