A lighter V8 · V8

In late 2018 we started a project called V8 Lite, aimed at dramatically reducing V8’s memory usage. Initially this project was envisioned as a separate Lite mode of V8 specifically aimed at low-memory mobile devices or embedder use-cases that care more about reduced memory usage than throughput execution speed. However, in the process of this work, we realized that many of the memory optimizations we had made for this Lite mode could be brought over to regular V8 thereby benefiting all users of V8.In this post we highlight some of the key optimizations we developed and the memory savings they provided in real-world workloads.
