How We Made GitHub Fast. Detailed overview of the new GitHub architecture. It’s a lot more complicated than I would have expected—lots of moving parts are involved in ensuring they can scale horizontally when they need to. Interesting components include nginx, Unicorn, Rails, DRBD, HAProxy, Redis, Erlang, memcached, SSH, git and a bunch of interesting new open source projects produced by the GitHub team such as BERT/Ernie and ProxyMachine. # 21st October 2009, 9:14 pm
Ravelry. Tim Bray interviews Casey Forbes, the single engineer behind Ravelry, the knitting community that serves 10 million Rails requests a day using just seven physical servers, MySQL, Sphinx, memcached, nginx, haproxy, passenger and Tokyo Cabinet. # 3rd September 2009, 6:50 pm
Building and Scaling a Startup on Rails: 12 Things We Learned the Hard Way. Lessons learned from Posterous. Some good advice in here, in particular “Memcache later: If you memcache first, you will never feel the pain and never learn how bad your database indexes and Rails queries are”. Also recommends using job queues for offline processing of anything that takes more than 200ms. # 23rd February 2009, 8:28 am

SELECT * FROM everything, or why databases are awesome. I’m beginning to think that for scalable applications the thinner your ORM is the better—if you even use one at all. # 22nd June 2007, 12:40 am
In the big picture, Twitter did exactly the right thing. They had a good idea and they buckled down and focused on delivering something as cool as possible as fast as possible, and it’s really hard, in early 2007, to beat Rails for that. When all of a sudden there were a few tens of thousands of people using it, then they went to work on the scaling.

Rails and Scaling with Multiple Databases. Ryan Tomayko explains how his team spreads a high traffic Rails application across five separate PostgreSQL databases by giving each client their own schema—similar to how WordPress MU scales. # 14th April 2007, 2:32 am
None of these scaling approaches are as fun and easy as developing for Rails. All the convenience methods and syntactical sugar that makes Rails such a pleasure for coders ends up being absolutely punishing, performance-wise.

A brief update with some numbers for hardware load-balanced mongrels. 4000 requests/second on 48 mongrels behind a hardware load balancer. # 5th February 2007, 12:38 am
punupgeek.com on Active Resource. Looks like 37 signals might be looking in to scaling across multiple servers using web services. # 26th June 2006, 11:12 am
Ruby on Rails and FastCGI: Scaling using processes instead of threads. Relates to the shared-nothing architecture. # 12th April 2005, 2:06 pm
