For those not familiar with Zynga's mega-hit Farmville, it is a Facebook-based virtual farming game. It has 75 million monthly users and 28 million people play each day.
Farmville is one of a growing number of hugely popular social games.
The High Scalability blog has a fascinating (but a bit geeky) article on the growth of Farmville. It contains Farmville's staggering stats:
The game had 1 million daily players after 4 days and 10 million after 60 days.
Currently, FarmVille has 28M daily players and 75M monthly players 9 months after launch. That makes the monthly player base of FarmVille larger than the entire population of France.
The amount of traffic between FarmVille and the Facebook platform is enormous: at peak, roughly 3 Gigabits/sec of traffic go between FarmVille and Facebook while our caching cluster serves another 1.5 Gigabits/sec to the application.
The business implications of these stats are far too great to list here. But one thing is clear, Facebook is a prime-time applications platform.
