Facebook numbers, quite impressive I say

How impressive? Schroepfer threw out some huge numbers. Among them:

  • Users spend 8 billion minutes online everyday using Facebook
  • There are some 2 billion pieces of content shared every week on the service
  • Users upload 2 billion photos each month
  • There are over 20 billion photos now on Facebook
  • During peak times, Facebook serves 1.2 million photos a second
  • Yesterday alone, Facebook served 5 billion API calls
  • There are 1.2 million users for every engineer at Facebook
And they are doing this with just php, mysql and memcached ?

nahhhh
