Are others experiencing noticeably slow response times in the past month or so? The time to go from page to page and back is much longer than other sites. This is a recent phenomenon, and is not happening on other sites.

Does IB track site performance through external 3rd party measurement sites? Is there some new ad delivery system that has been deployed? During the delayed response I see access to "api.permutive.com", whatever that is.

Just me?

ETA: Typically use Firefox, but similar issue using Chrome
