Start with the benchmark command in the Repro section and the referenced performance reports for the two WinForms startup scenarios. Read performance/scripts/benchmarks_ci.py and the linked benchmarking workflow to understand how the runs are produced. The issue does not name a code change or acceptance criteria, so a completed fix is not defined.
