# Report Metrics Breakdown

In the **Report Metrics Breakdown**, the following metrics are used to assess performance degradation:

<table><thead><tr><th width="152">Metric</th><th>Description</th></tr></thead><tbody><tr><td><strong>Binary</strong></td><td>Specify the binary name containing the function.</td></tr><tr><td><strong>Function</strong></td><td>The name of the function.</td></tr><tr><td><strong>Response</strong></td><td>Response Time [ns]: The average (mean) execution time of a function.</td></tr><tr><td><strong>Throughput</strong></td><td>Top deviated metric shows the functions that have the biggest change in absolute time of execution or in other words the functions with biggest delta in the execution time (throughput).</td></tr><tr><td><strong>Bottleneck</strong></td><td>This metric highlights the functions with the most significant performance bottlenecks, focusing on the most time consuming segment of code within one function, that doesn't include the execution time of the callee function (i.e., caller > callee).</td></tr><tr><td><strong>Diff [%]</strong></td><td>The percentage difference in execution time between the Base and Target versions. A positive value indicates a speed up, while a negative value indicates slowing down.</td></tr></tbody></table>
