So this mean the most time consuming is PDF processing, displaying page is only ~10% of time... I'm thinking now that maybe I do worthless PDF page render when scrolling! I cannot check source now but when I'll be back at home... For scrolling I need just adjust y_offset and redraw the sceen. If so, it could bring heavy speed up!
