Your reader is way too slow. Mine opens a new book in 7-9 seconds and turns page in 1 second, aprox. I'm talking about a "normal" fb2 book (1, 2... 3 MBytes at most).
I have to agree with leandroide. Your reader is much slower than mine. Having said that, I just recently flashed the OpenInkPot firmware for mine. It has some nicer capabilities and with the latest update, you can delete books from the reader. You can download it here
. You may want to gain more familiarity with your reader before you try this.
