Measuring Performance
We’ve integrated with the User Timing API to be able to show some performance measurements of our client script. The supported measurements are:
nosto.get_dynamic_placements Parse the DOM and find placements on the page. Performed before a recommendations request is sent.
nosto.load_recommendations Send the recommendations request and handle the recommendation result. This encompasses measuring the recommendations request and nosto.inject_campaigns.
nosto.inject_campaigns Inject both dynamic and static campaigns into the DOM. This encompasses both nosto.inject_static_campaigns and nosto.inject_dynamic_campaigns.
nosto.inject_static_campaigns Inject static campaigns into the DOM.
nosto.inject_dynamic_campaigns Inject dynamic campaigns into the DOM.
nosto.evaluate_js Extract and evaluate embedded JavaScript from recommendation templates.
Lighthouse
Chrome's lighthouse tool can be opened by doing the following:
1.Right click and select Inspect.
2.Navigate to the Lighthouse tab.
3.Ensure the Performance category is enabled.
4.Click Generate Report
​
​
​
Once the report is generated, you can expand the “User Timing marks and measures” section under the Diagnostics section to see some basic information like how long after the page started to load the measurements start and how long each measurement took.
You can scroll back up and click the View Original Trace button to view a timeline of the measurements. You may need to expand the Timings section to view the client script’s recorded measurements. You can zoom in an out of this graph and swipe side to side to get a better view of things.
