John Adams on Fixing Twitter: Improving the Performance and Scalability of the World’s Most Popular Micro-blogging Site

Twitter is suffering outages today as they fend off a Denial of Service attack, and so I thought it would be helpful to post John Adams’ exceptional Velocity session about Operations at Twitter.

Velocity and the Bottom Line

Velocity and the Bottom Line

Velocity 2009 took place last week in San Jose, with Jesse Robbins
and I serving as co-chairs. Back in
November 2008, while we were planning Velocity, I said I wanted to highlight “best practices in performance and operations that improve the user experience as well as the company’s bottom line.” Much of my work focuses on the how of improving performance – tips developers use to create even faster web sites.

The psychology of engineering user experiences on the web can be difficult. How much rich content can you place up on a page before the load time drives away your visitors? Get the answer wrong, and you can end up with a ghost town; get it right and you’re a star. Eric Schurman knows this well, since he is responsible for just those kind of trade-off decisions on some of Microsoft’s highest traffic pages. He’ll be speaking at O’Reilly’s Velocity Conference in June, and he recently talked with us about how Microsoft tests different user experiences on small groups of visitors.

Velocity Preview – Keeping Twitter Tweeting

Velocity Preview – Keeping Twitter Tweeting

If there’s a site that exemplifies explosive growth, it has to be Twitter. It seems like everywhere you look, someone is Tweeting, or talking about Tweeting, or Tweeting about Tweeting. Keeping the site responsive under that type of increase is no easy job, but it’s one that John Adams has to deal with every day, working in Twitter Operations. He’ll be talking about that work at O’Reilly’s Velocity Conference, in a session entitled Fixing Twitter: Improving the Performance and Scalability of the World’s Most Popular Micro-blogging Site, and he spent some time with us to talk about what is involved in keeping the site alive.
