Start with the System.Tests.Perf_Random.NextSingle benchmark and the provided benchmarks_ci.py command in dotnet/performance. Reproduce the Windows x64 result, then inspect the linked comparison and profiling reports to determine whether the improvement is real and what follow-up is required; the issue gives no specific code change or completion test.
