cafPdm_CompileBench — Compile Time Benchmark

Configuration

Setting	Value
Compiler	MSVC (cl.exe)
Build system	Ninja
Parallelism	2 cores
buildcache	disabled
Precompiled headers	disabled
Unity build	disabled

The benchmark target is an OBJECT library with UNITY_BUILD OFF, so each translation unit is compiled in isolation. Times are wall-clock milliseconds read from .ninja_log (finish_time - start_time). Each run is a full clean rebuild (ninja -t clean cafPdm_CompileBench followed by rebuild).

Baseline — 2 cores, 3 runs — branch pdm-compile-bench-01, commit e5577fda8 (2026-04-06)

Notes

• The benchmark files exercise different combinations of PDM field types:
  • bench_filepath_fields — caf::FilePath fields
  • bench_basic_fields — primitive field types (int, double, bool, QString)
  • bench_container_fields — std::vector container fields
  • bench_enum_fields — enum fields with AppEnum
  • bench_mixed_fields — mix of all field types
• bench_mixed_fields is the heaviest translation unit and is the most representative proxy for a real PDM object with diverse field usage.
