Stuff I like

The test participant in the top gaze plot fixated a few times within the big empty color block before the content downloaded, then spent the remaining time looking at the rest of the page. This user never looked at the big promotional space after it had rendered.
The second user (bottom gaze plot) happened to be looking away from the screen during the 8 seconds when the promotional content downloaded. Thus, the first time he looked at the page he saw it as intended, complete with the entire promo.
The slideshow occupies 23% of the page, not counting a footer that’s not shown here. The user who had to endure the download delay spent only 1% of her total viewing time within this space. In contrast, the user who in effect received instantaneous page rendering (because he didn’t look until it was done), spent 20% of his viewing time within the slideshow area.Website Response Times (Jakob Nielsen’s Alertbox)
