Some Facebook huge numbers

Fantastic Facebook Facts
Amin Vahdat, a professor in Computer Science and Engineering at 
University of California San Diego, writes a blog called "Idle Process."

         He recently had the opportunity to host a talk by Jeff 
Rothschild, vice president of technology at Facebook.

         The presentation was called, "High Performance at massive 
Scale: Lessons Learned at Facebook."

         If you're a sucker for stats, here are some of the 
highlights jotted down by Vahdat during the talk- it's amazing Stuff.

         Facebook is the No. 2 property on the Internet, as measured 
by the time users spend on the site.

         It runs about 30,000 servers (the bulk acting as Web 
servers) and gets more than 200 billion monthly page views.

         Facebook processes 3.9 trillion feed actions per day,
         stores 20 billion photos in four resolutions,
         handles 2 billion to 3 billion new uploaded photos every month
         serves 600,000 photos every second (serving them is more 
difficult than storing them, it seems).

         It had originally provisioned photo storage for six months, 
but blew through available storage in 1 1/2 weeks. And that's just 
the beginning.
