feat: add Profile-Guided Optimization (PGO) support
- Add comprehensive PGO module in internal/tools/pgo/
- Integrate PGO into dtail-tools command with full CLI support
- Add Makefile targets for PGO workflow:
- make pgo: Full PGO workflow
- make pgo-quick: Quick PGO with smaller datasets
- make pgo-generate: Generate profiles only
- make build-pgo: Build with existing profiles
- make install-pgo: Install optimized binaries
- Add convenience functions to data generator for PGO
- Document PGO workflow in CLAUDE.md
Performance improvements observed:
- DCat: 3.8-7.0% additional improvement over turbo mode
- DGrep: Up to 19% improvement for low hit rates
- DMap: Variable impact, up to 64% for min_max on large files
Benchmarks show total performance gains (pre-turbo → turbo+PGO):
- DCat: 14-21x faster
- DGrep: 9-15x faster
- DMap: 9-29% faster

@@ -1,3 +1 @@ # To-do's - -* In turbo mode, Perform PGO (profile-guided optimization) on the dcat, dgrep and dmap commands. Compare benchmarks before and after and create a new baseline for it in ./benchmarks/baselines. For the PGO, create a similar framework as the benchmarking. You can code the PGO procedure as an option to the dtail-tools command. Use the benchmark files for the PGO as a reference. Once implemented and working, you can remove this item from the todo list here. |
