Google Chrome developers have prepared Crankshaft, a new compilation infrastructure that will give Chrome's V8 JavaScript engine a major performance boost. The new optimizations promise massive performance enhancements for compute-intensive JavaScript applications, often by more than a factor of two. The full details can be found at
The Chromium Blog.
The benchmarks that benefit the most from Crankshaft are Richards, DeltaBlue and Crypto. This shows that we have taken the performance of JavaScript property accesses, arithmetic operations, tight loops, and function calls to the next level. Overall, Crankshaft boosts V8’s performance by 50% on the V8 benchmark suite. This is the biggest performance improvement since we launched Chrome in 2008.
In addition to improving peak performance as measured by the V8 benchmark suite, Crankshaft also improves the start-up time of web applications such as GMail. Our page cycler benchmarks show that Crankshaft improves the page load performance of Chrome by 12% for pages that contain significant amounts of JavaScript code.
