John Resig: Drop-in JavaScript Performance

February 9, 2009 11:32 pm | 1 Comment

I wrote a post on the Google Code Blog about John Resig’s tech talk “Drop-in JavaScript Performance.” The video and slides are now available.

In this talk, John starts off highlighting why performance will improve in the next generation of browsers, thanks to advances in JavaScript engines and new features such as process per tab and parallel script loading. He digs deeper into JavaScript performance, touching on shaping, tracing, just-in-time compilation, and the various benchmarks (SunSpider, Dromaeo, and V8 benchmark). John plugs my UA Profiler, with its tests for simultaneous connections, parallel script loading, and link prefetching. He wraps up with a collection of many other advanced features in the areas of communiction, DOM, styling, data, and measurements.
