I've noticed that since getting into G+ my Gmail tab in safari constantly has the spinner showing. (OS X) I suspect the new status bar at the top is doing some aggressive polling or long-polling to get notifications. That said, I have not experienced any of the problems the author describes, and I think it's telling that he does not mention his system specs, or the browsers effected, or his network conditions. Maybe he's behind a firewall that munges the Accepts-Encoding header, defeating gzip.
