How often is Friendfeed hitting Flickr, and how many Friendfeed users are on Flickr?
We now have a glimpse into Monday's traffic, thanks to a snapshot provided by Kellan and Rabble's in their talk, Beyond Rest: Building Data Services with XMPP PubSub, presented earlier today at OSCON in Portland:
On July 21, 2008, Friendfeed hit Flickr 2.9 million times to get the latest photos of 45,754 users, of which 6,721 visited Flickr in that 24-hour period, and could have potentially uploaded a photo.
Three million requests for 6,000 updates. Clearly, polling isn't ideal. Don't miss the rest of the slides.
(Also, at its peak, Flickr is currently receiving 60 uploaded photos a second, "roughly 10 times the number of people born on Earth per second.")
