 ## Measure custom metrics
 
-Through k6 browser's `page.evaluate` function, you can call the [Performance API](https://developer.mozilla.org/en-US/docs/Web/API/Performance_API) to measure the performance of web applications. As an example, if you want to measure the time it takes for your users to complete actions, such as a search feature, then you can use the [`performance.mark`](https://developer.mozilla.org/en-US/docs/Web/API/Performance/mark) method to add a timestamp in your browser's performance timeline.

 # Hybrid performance with k6 browser
 
-An alternative approach to [browser-based load testing](https://grafana.com/docs/k6/<K6_VERSION>/testing-guides/load-testing-websites/#browser-based-load-testing) that is much less resource-intensive is combining a low amount of virtual users for a browser test with a high amount of virtual users for a protocol-level test.

-Hybrid performance can be achieved in multiple ways, often using different tools. To simplify the developer experience, k6 browser can be easily combined with core k6 features, so you can easily write hybrid tests in a single script.

-The code below shows an example of combining a browser and HTTP test in a single script. While the backend is exposed to the typical load, the frontend is also checked for any unexpected issues. Thresholds are defined to check both HTTP and browser metrics against pre-defined SLOs.

 ## Browser and failure injection test
 
-A browser test can also be run with a failure injection test via the [xk6-disruptor](https://github.com/grafana/xk6-disruptor) extension. This approach lets you find issues in your front end if any services it depends on are suddenly injected with failures, such as delays or server errors.

 ## Recommended practices
 
-- **Do start small**. Start with a low amount of browser-based virtual users. A good starting point is to have 10% virtual users or less to monitor the user experience for your end-users, while around 90% of traffic should be emulated from the protocol level.

 - **Combine browser test with different load testing types**. To fully understand the impact of different traffic patterns on your end-user experience, experiment with running your browser test with different [load testing types](https://grafana.com/docs/k6/<K6_VERSION>/testing-guides/test-types/).
-- **Cover high-risk user journeys as a start**. Consider identifying the high-risk user journeys first so you can start to monitor the web performance metrics for these user journeys while your backend applications are being exposed to high traffic or service faults.
