Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030619 Netscape/7.1 (ax) Goto a long page with text/images and scroll up/down using the arrow keys. The CPU pegs out and the scrolling becomes v e r y s l o w.
Example URL ?
No, that only got me up to 25% CPU. (Is that high for a page like this? I don't know.) I was browsing through http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Overview2.html when I experienced this. It was most notable when the images were in view. The higher CPU usage seemed to correspond to bringing new content into view. If I reverse and scroll through previously seen content it seemed much faster.
