Google Reader Numbers

I found this page (thanks to mr Schoble) with some Google Reader.
  • Google Reader uses 10 TB for storing all the raw data
  • Google Reader crawls 8 million feeds
  • Search requires a lot of computational resources. Google Reader uses two indexes for search:- a big tree updated twice a day (150machines, 600 million documents)- 40 small trees for recent posts, updated every 5 minutes (40 machines, 40million documents)
