BBC:
Ads are responsible for making webpages slow to a crawl, suggests analysis of the most popular one million websites.
The research by developer Patrick Hulce looked at which chunks of code take longest to load.
About 60% of the total loading time of a page was caused by scripts that place adverts or analyse what users do, he found.
Not news for most Soylentils, but in case anyone needs to cite the performance hit (to convince PHBs)...

Indeed, 60% seems like the lower limit of the loading time increase...
My Local newspaper's website, the index page is 316 KB, of that, 300 KB is a wankfest of mostly ad and tracking JavaScript..and this script has the further audacity to load even more obfuscated javascript shitfuckwankery off the developer's own poxy little site...I reckon all that accounts for between 80-90% of that page's loading time...and then it falls over and dies unless you've a multicore CPU and several gig of ram..
The recent El Reg redesign has seriously increased their page loading time, I think there's 200K of javascript on their index page (cant check, am using a shitty old ipad at present) and when it does eventually sort of load, the site is almost unusable on older browsers/hardware which rendered their old site design without issue..
