When building Highlight, we've made technical decisions that prioritize putting your site's performance first. Highlight's performance impact on your site, therefore, is negligible, both from the perspective of your user's real-time experience as well as from a page-load perspective.
Highlight's bundle size is a mear 35 kb as seen here. From a page load perspective, your team should have no qualms regarding Highlight's impact on page load metrics.
Highlight uses the well-maintained
DomMutationObserver spec in order to record DOM mutations. When sending these changes to our platform, we buffer events periodically to ensure that 1) events aren't being held in memory for a prolonged time and 2) outgoing network requests aren't interfering with user interactions.
Your client will send Highlight telemetry about every 5 seconds. We've taken extra care in making sure we don't overwhelm your end user's machine:
- Only 1 request will be in-flight at a given time
- Responsive to your end user's network speed
