Preview scrolling very slow

Hi there. So I am new to the macworld and i am using preview to view pdf and i like to use the arrow keys on the keyboard to scroll when reading pdf files in adobe reader. when using preview i notice it scrolls down very slow. it works good if i use the mouse but i like to use the arrow keys...is there a way to solve this?

With Preview i can use arrow keys to move a page at a time, but have not found the settings other than clicking on page then using arrow keys seems to vary the response. One arrow press will also go 4 pages at a time but yet to sort the command to invoke it.
