Datadog has an internal infrastructure of continuous benchmarking. There is an internal set of UI tests that run on a special benchmark application for every change made to the SDK. This way Datadog is able to detect performance regression early to ensure that they are prevented from reaching production releases.

## Overview
16+
17+
When integrating any SDK into your iOS application, understanding its performance impact is crucial for maintaining a smooth user experience. The Datadog RUM SDK is designed with minimal performance overhead. Use these benchmarks to evaluate whether the SDK fits your app's performance budget and plan your integration accordingly.
