Execution-Time Benchmarks Report ⏱️Execution-time results for samples comparing This PR (8225) and master. ✅ No regressions detected - check the details below Full Metrics ComparisonFakeDbCommand
HttpMessageHandler
Comparison explanationExecution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:
Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard. Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).

Summary of changes
Generate reference chain at type level
Reason for change
Last step to help pointing out memory leaks root cause (i.e. which root is responsible for keeping instances alive)
Implementation details
Listen to GC_BULK_ROOT_STATIC_VAR and GC_BULK_ROOT_EDGE to get the different kinds of root. Next, traverse the reference fields down to a leak (i.e. non reference object). The reference chain is kept at the type level to avoid consumming to much memory and serialized in .json format to be sent with profile data.
Test coverage
Unit tests and integration tests have been added.
