The latest CE is now starting to roll out as a national update and it helps a bit with the speed. And don't forget, in the display settings change the scrolling effects to off, it helps a little bit scrolling through the guide.
Also, do know how to change the 30second slip to a 30 second skip?
If I remember correctly, you do a keyword search 30SKIP. Get back to the slip mode by doing the same using 30SLIP. There maybe a space between the 30 and the word.
