I'm trying to read a book in PDF format that has images and text. Scrolling through pages is very slow and if I scroll too fast it takes a few to load the page.

Is there a setting anywhere that I can fiddle with so Adode uses more resources to load pages faster?

(I looked at the Page Display Preferences, not to be a Mac-hater, even though I am, the setting are all dumbed down and nothing seems to tailored to what I want to achieve) Looked for a slider, a drop down menu that I can allocated a certain amount of RAM to be used by Adobe. nope nothing.

Should note this is Adobe Reader XI 11.0.5

Scrolling is all about CPU (I assume this because when I continuously scroll, my CPU usage goes skyrocket to 100%). If you are on balanced power settings or have a slow CPU, it will be laggy. – Varaquilex Jan 27 '14 at 0:38

Try updating Adobe Reader to latest version (11.0.6) and see whether it makes any difference. – and31415 Jan 27 '14 at 1:06
    
Pages that are fully images will be slow, so if you happen to have the file and can run the OCR on it and save it again, I'd give that a try. Check out adobe.com/products/acrobat/convert-jpeg-scan-ocr-to-pdf.html – JamesTheDev Jan 27 '14 at 4:57
    
try a different tool and look if this is also slow – magicandre1981 Jan 27 '14 at 5:01

I could recommend you use another PDF reader.

Here there is some alternatives : http://www.pcworld.com/article/2027961/ditch-the-pdf-headaches-three-safer-speedier-adobe-reader-alternatives.html

I personally had used Sumatra PDF and works simple and fast.

Recommending products is a No, no. OP is asking why Large pdf files are lagging, not an alternative piece of software – Sickest Jan 27 '14 at 0:42
