调研方向

Start with the linked baseline/compare diff and the performance report, then review GetServiceBenchmark.cs and CtorFromCollectionNonGeneric.cs. Run the documented benchmarks_ci.py command and compare the ARM64 AzureLinux results against the supplied baseline. Done means identifying and addressing the reported regressions, with the benchmark results confirming the change.
