Ah, hubris. Try simulating some celebrities talking to one another. 15M followers (Ashton Kutcher) / 10K fanouts per second = 25 minutes to deliver one tweet.

That's the difference between "getting the basic process running" and operating at scale.

Ehh, first off the 2009 twitter was vary different than the 2014 beast. For some context: http://computer.howstuffworks.com/internet/social-networking...

Back when they where growing from 500,000 users to 7 million total users they where having major issues and that's when I was looking into things.

Anyway, not I was suggesting 1GB would be fine today. Still, I was saturating a 1GB connection so 15M (over twice the total users back then) * ~200bytes * 8 / ~1000^3 = ~24 seconds did you have an extra 60x multiplier in there somewhere?
