Start with the benchmark sources at src/benchmarks/micro/libraries/System.Net.NetworkInformation/NetworkInterfaceTests.cs and src/benchmarks/micro/libraries/System.Diagnostics/Perf_Process.cs, then run the documented benchmarks_ci.py filters on Ubuntu. Compare the reported baseline and test timings and consult the linked profiling and benchmarking workflow documents. The issue does not define a code change or a clear completion condition.
