RoboHornet includes all aspects of a browser’s performance and other important matters for web developers, such as layout performance and localStorage, but it is still in an early alpha state.
“[...] That’s where you come in,” announced RoboHornet leader Alex Komoroske in a Google+ post. “It’s up to you and to propose and vote for performance issues you care about, helping shape the future of the benchmark and effectively defining the areas that browser vendors will invest in making run faster.”
Google engineer Paul Irish further detailed on his blog how RoboHornet plans to test many browser facets.
“These days, our performance bottlenecks are oftentimes DOM, <canvas> API methods, SVG. Those are our priorities,” explained Irish. “So we wanted to solve that with RoboHornet.”
