    I have just noticed this since doing the update.

    Go to a website, I used engadget as it's a good heavy one to test, the very start of the web site comes up, then start scrolling the screen down the web site to the bottom, then up again to the top, then down again.

    The loading of the site stops dead in it's tracks till you stop scrolling.

    I'm sure it did not do this before, yes, it slowed it down, but I'm sure it kept loading.

    It almost seems like today's 4.3 update has changed something and now scrolling is taking 100% iPad power and no new data can be displayed till you stop.

    Is this just me, I can't go back to 4.2 now to double check.

    Whilst 4.3 does indeed render the web site faster which is great. I'm sure I used to be able to scroll down and the data kept coming in/being displayed, unlike now where the blue downloading bar stops dead till you stop scrolling.

    Anyone confirm this change?

    This is most likely due to all currently available hardware being a single core. The loading is on a background thread, and scrolling on the foreground. When you scroll the processor spends all or most of its time handling that. I'm really hoping this is the reason. That would mean the iPad 2 will scroll & load at the same time since its a dual core.

    I think scrolling in Safari is much worse on an iPad 1 since 4.3. It is much smoother in the Atomic browser which has (not yet) been "optimized" for dual core. The problem is pretty severe on the Google News site. It is like the page 'sticks' when scrolling, then suddenly breaks free. I often launch links when I intend to scroll. To be fair, I don't think I tried this site before 4.3; however, in the Atomic browser, the scrolling is smooth.
