Improving Performance by Changing the Rules - From Fast to SPDY

Ido Safruti (PerimeterX), Mike Belshe (BitGo)

SPDY was proposed by Google back in November 2009 to reduce the latency and load time of web pages. It was provided as part of the Chromium open-source project and is enabled in Chrome by default.

We at Cotendo took on the challenge, implemented the server side, and extended our proxies to support SPDY, providing SPDY to HTTP “translation”. Guess what? It really speeds things up. But like all new good things, there is still work to do. We will share insights from our implementation, optimization of SSL-based traffic and present performance data both from Google’s and our customers’ deployment.

What’s next?

We believe the introduction of SPDY as a new application layer presents a unique opportunity to rethink web design concepts and front-end-optimization (FEO) techniques. We will discuss some optimizations we developed and suggest some guidelines on how you can approach these new types of optimizations.

Mike Belshe has been an early member of the Google Chrome team, working on a number of performance-related areas including network speed, plugins, and javascript performance. Mike has worked at several startups in silicon valley over the last 15 years, including Netscape, Remarq, Good Technology, and Lookout Software. His performance work for the web started in 1995 when he was a lead engineer on the Netscape Enterprise Server 2.0 team. Ironically, he never thought he’d ever be working on browsers back then.

I have seen Mike present SPDY before, however, I still found myself fascinated to hear about SPDY again. I look forward to seeing the impact SPDY has on making the web faster.
