Start with the benchmark source at src/benchmarks/micro/libraries/System.Collections/CreateAddAndClear.cs#L132-L142 and run the provided benchmarks_ci.py command. Compare the linked baseline, test, and report for the SortedList case; the issue does not define a code change or acceptance condition, so a maintainer must clarify what should be done.
