# Performance improvements after browser version update

You may notice performance improvements in Web and Transaction tests after a node browser agent version gets updated. Version updates add new features to the browsers which may result in improved performance.

For example, the V8 JavaScript engine that these updated browsers utilize interprets JavaScript instructions and then compiles them into programs that can run in the browser. The performance increase comes from new background components of the V8 JavaScript engine that are now the exclusive components used in the pipeline for running JavaScript applications. This is likely to make the biggest difference in pages that are very JavaScript-heavy.

Catchpoint gives you the ability to run tests using different Chrome versions. For more information on how to switch different Chrome version, please see this article: [Choose Your Chrome Version](https://docs.catchpoint.com/docs/choose-your-chrome-version)
