difference between parsing rss and "executing" json?

Scott's SiteExperts Place: What we learned building (or why are we slow)?:
As a simple benchmark, on my fast developer machine we went from 400ms to parse 150K of RSS to 15ms to “execute” the JSON response.

Whats the difference between parsing RSS and "executing" JSON? I assume by execute he means parsing data in the JSON format, and then doing something with it. In which case thats a big speed up. I wonder which browser/browser gave him those numbers, and how other browser did in comparision.

Yahoo it seems makes good use of JSON. can send output in JSON format, which is how the recent links on the top of my side bar show up (thanks jon udell).
