Start with the benchmark sources src/benchmarks/micro/runtime/Struct/GSeq.cs and src/benchmarks/micro/runtime/Benchstones/BenchI/MulMatrix.cs, then run the provided benchmarks_ci.py commands on Windows/x86. Compare the linked baseline and test reports to understand the reported improvements. The issue does not define a requested code change or acceptance criterion, so confirm the intended action with maintainers first.
