Impressive presentation about whiteboxing WebKit and Chrome by Ilya Grigorik . I strongly recommend flags that are on slide 21: (Network internals of Chrome) http://www.igvita.com/slides/2012/web-performance-for-the-curious/#21 chrome://predictors - omnibox predictor stats (tip: check 'Filter zero confidences') chrome://net-internals#sockets - current socket pool status chrome://net-internals#dns - Chrome's in-memory DNS cache chrome://histograms/DNS - histograms of your DNS performance chrome://dns - startup prefetch list and subresource host cache 60FPS is not only about games but pages too, so keep an eye on how much code you execute eg. on scroll event. 60FPS affords you a 16.6ms budget per frame http://www.igvita.com/slides/2012/web-performance-for-the-curious/#33 We can use GPU by: Forcing a GPU layer: -webkit-transform:translateZ(0) GPU is really fast at compositing, matrix operations and alpha blends http://www.igvita.com/slides/2012
