Why does it lag so much when I scroll in Safari? (OS X Lion)

Question

I've noticed that ever since the OS X Lion update, webpages in general are pretty laggy when scrolling.  I let the page completely load and when I scrollthere is stuttering and lag.  It is made most apparent when I use momentum to scroll a long webpage.
It seems to happen mostly with more complex pages (which makes sense I guess).  For example, some parts of NYTimes.com doesn't have much lag when scrolling.  But most websites (like mine: http://wistfulwriter.com) are pretty laggy.  I know I use a background image and use special fonts, but I never had this problem before the Lion update.  Many other sites lag too: CNN.com, WashingtonPost.com, etc.  It seems like any time there is an image, there is stuttering.
I have tried setting the zoom level to default (command-0) just in case, and I have exited unnecessary applications and everything.  The lag is still there, regardless if I use fullscreen mode or not (though on some sites it is not as noticable in windowed mode).
Any clues?  Thanks!

Clay G wrote this on another thread so I'll give you his suggestions and it WORKED FOR ME!
Go to FINDER-LIBRARY-PREFERENCES- and delete the folder com.apple.safari.rss.plist
Go to FINDER-LIBRARY-CACHES- and delete the folder com.apple.safari
Restart your Mac.
I too was experiencing some severe lagging in some web sites-using Safari.
Also heard that Adobe (v 10.1) can cause lagging problems. V. 10.0 is more stable.
Did what Clay offered and NO MORE LAGGING.
BTW, you'll have to do a search(SPOTLIGHT) for SAFARI but it pops right up and you still have all your bookmarks and favorites.
Hope this helped.
