FAQPage Schema
How do I detect performance regressions in a web application?

You can detect web performance regressions by comparing page load times, Core Web Vitals, and resource sizes before and after changes. This Skill automates that comparison by gathering performance data from running pages to identify issues introduced by new deployments.

What metrics are used to benchmark page speed?

Benchmarking page speed involves measuring Core Web Vitals, page load times, and resource sizes. This Skill collects these specific performance metrics from running pages to provide a detailed performance audit for web development workflows.

How do I run a performance audit on a specific URL?

To run a performance audit on a URL, you use the benchmark skill to evaluate the target web page. It utilizes a browse daemon's perf command and JavaScript evaluation to gather and report the performance data for the specified address.

Do I need gstack to benchmark page speed?

Yes, you need the gstack dependency to benchmark page speed. The Skill requires gstack to successfully gather performance data from running pages and execute the underlying performance evaluation commands.

Can I compare web page performance before and after a deployment?

Yes, you can compare web page performance before and after a deployment. The Skill detects performance regressions by benchmarking page speed metrics from a previous version against the newly deployed version to identify any potential issues.

What is the best way to measure Core Web Vitals for performance regression testing?

The best way to measure Core Web Vitals for regression testing is to use a benchmarking tool that compares resource sizes and load times before and after changes. This Skill captures those metrics from running pages to ensure applications remain optimized.
