Start with src/benchmarks/micro/libraries/System.Runtime.Numerics/Perf.BigInteger.cs at lines 34-37 and read the benchmarking workflow linked in the issue. Run the provided benchmarks_ci.py command with the System.Numerics.Tests.Perf_BigInteger filter, then compare the Parse results under the stated AOT and wasm configuration. Done means the reported improvement is reproduced and its cause or required follow-up is established.
