Over the last year the V8 team has developed a new methodology to measure and understand real-world JavaScript performance. We’ve used the insights that we gleaned from it to change how the V8 team makes JavaScript faster. Our new real-world focus represents a significant shift from our traditional performance focus. We’re confident that as we continue to apply this methodology in 2017, it will significantly improve users’ and developers’ ability to rely on predictable performance from V8 for real-world JavaScript in both Chrome and Node.js.

Memory consumption is an important dimension in the JavaScript virtual machine performance trade-off space. Over the last few months the V8 team analyzed and significantly reduced the memory footprint of several websites that were identified as representative of modern web development patterns. In this blog post we present the workloads and tools we used in our analysis, outline memory optimizations in the garbage collector, and show how we reduced memory consumed by V8’s parser and its compilers.
