Experience increases the speed. Reading on computer screens and backlit devices naturally slows reading a further 25% Lots of reasons for that. So reading pdf files most people read slower in the first place.
Look at the traditional reading times. Most people have told me that time it takes is between 6 and 12 hours to read a 200 page book (interesting survey that I did on a university campus, handing them a book of 200 pages and asked how long it would take to read it.) No one aid less than 6 hours, many said 12 hours and others said they wouldn't even finish it.
So 6 hours for a book plus 25% on e-devices, spending 1.5 hours in total is excellent for a beginner. Once you have activation as a second nature you'll probably find what you need faster.
Keep experimenting and playing with the system. Once you make it yours you'll refine further.
