To download the Page Optimizer, in Experience Builder, click ![Settings](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_settings.png) on the left sidebar, and then click **Advanced**.

After installation, the Page Optimizer is located with your other Chrome extensions.

![Community Page Optimizer](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_performance_tool.png)

## Insights

To analyze your site, navigate to your published site, load the page, and then launch the Page Optimizer.

![Community Page Optimizer Insights tab](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_perf_insights.png)

The Insights tab (1) evaluates your page based on best practices for web applications developed using the Lightning framework. This tab displays an overall performance score (3) along with individual scores (5) for various analysis rules. To view details and suggested actions, click each rule. For more room to work, click **Popout** (2).

The Insights tab is conservative in providing recommendations. For further insights, consider reviewing the raw data presented on the Waterfall, Timeline, Charts, Cost, and Actions tabs.

To remove collected metrics, click **Clear** (4). Perform some user actions on the page to collect new metrics, and then reopen the Page Optimizer. For example, to gather performance metrics for liking a feed item, clear performance metrics, click Like, and reopen the Page Optimizer.

## Waterfall

The Waterfall tab displays all network requests and performance instrumentation data. Click a row to view contextual information in the sidebar. Click the arrow to the left of each row to expand the information for each row.

## Timeline

The Timeline tab provides a profile of each component’s rendering lifecycle. The timeline view is optimized for displaying Lightning framework metrics, so it’s easier to interpret than Chrome DevTools.

![Community Page Optimizer Timeline tab](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_perf_timeline.png)

## Charts

The Charts tab displays trending information about memory and components as customers use your page.

![Community Page Optimizer Chart tab](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_perf_chart.png)

## Components

The Components tab displays the lifecycle counts for each component on the page. This view helps you identify potential component leaks and unexpected rendering behavior. Use the Component tab along with the Cost tab for an overall view of component performance.

![Community Page Optimizer Components tab](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_perf_components.png)

## Cost

The Cost tab displays the amount of time each component was busy processing its logic. The lower the time, the better the performance.

![Community Page Optimizer Cost tab](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-experience-communities-264-0-0-production-enus/bf7df212-91a1-4fa3-a007-4d6f3e3b470b/communities/images/community_builder_perf_cost.png)

## Actions

The Actions tab displays a list of all actions performed on the page along with their timing information.

## Export

Export your analysis to a file to share with your development and support teams.
