What Does My Site Cost?
The site is ~~wrong~~ somewhat correct about how big reddits homepage is.<p>~~It seems to not run any scripts when testing, so 1.5MB is the basic JS + CSS.~~<p>In reality, it's much, much worse. (On a desktop)<p>Even with an adblocker, reddit.com downloaded 18MB in the first 10 seconds. That would put that cost at over $1.<p>I stopped after that because it seemed to be just continuously downloading... something.<p>I know Reddit is quite media driven these days, but it seems to be unnecessary prefetching a lot<p>Edit: Looks like I was testing the desktop version,   
see jefftk's reply.<p>However, it doesn't help reddit's case that much. After looking into what it's actually downloading in my "desktop" test, there are lots of huge PNG images (1000x1000 +) that seem to be displayed as tiny thumbnails.<p>And for an infinitely scrolling page, it prefetches all the images in the feed at full resolution.<p>If I turn off my adblocker, I get an autoplaying amazon ad (~5MB).<p>Additionally, it starts auto-playing a livestreams which is just below the fold.
