Here’s a great introduction to Twitter. You can follow me on Twitter here: http://twitter.com/lojic
I didn’t realize that Twitter was a Ruby on Rails app when I started researching it recently. This post on DHH’s blog informed me of that. The entry references an interview with a Twitter developer about their scaling issues.
By various metrics Twitter is the biggest Rails site on the net right now.
And from DHH’s blog:
Twitter is an amazing success story in terms of rapid user uptake and flattering press. I had a chance to speak with the team a while back about the wild ride they’ve been on. At that time they were fielding spikes of up to 11,000 requests per second across some 16 cores with very little caching thrown into the mix to mitigate. No wonder their site had been feeling slow.
Since I’m currently developing a Ruby on Rails app that has some significant performance requirements, it’s good to see that they’ve been able to handle 11,000 requests per second even if they’re struggling with scaling issues.
