Changes: - scripts/box/pgo_fast_profile_config.sh: Expanded WS patterns (3→5) and seeds (1→3) for reduced overfitting and better production workload representativeness - PERFORMANCE_TARGETS_SCORECARD.md: Phase 68 baseline promoted (61.614M = 50.93%) - CURRENT_TASK.md: Phase 68 marked complete, Phase 67a (layout tax forensics) set Active Results: - 10-run verification: +1.19% vs Phase 66 baseline (GO, >+1.0% threshold) - M1 milestone: 50.93% of mimalloc (target 50%, exceeded by +0.93pp) - Stability: 10-run mean/median with <2.1% CV 🤖 Generated with Claude Code Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

# Box: PGO Profile Configuration (FAST minimal)
|
|
# Purpose: Define representative workloads for FAST minimal PGO collection.
|
|
# Contract:
|
|
# - Only deterministic workloads (fixed args/seeds).
|
|
# - Must complete quickly per workload (PGO box enforces timeout).
|
|
# - Keep baseline toolchain consistent (GCC + LTO; profile-generate/use handled by Makefile).
|
|
|
|
# Binaries to profile (must exist after `make pgo-fast-profile`)
|
|

|
# Representative workloads (deterministic).
|
|
#
|
|
# Notes:
|
|
# - Keep these as shell strings: pgo_tiny_profile_box.sh runs them via `bash -lc`.
|
|
# - Prefer the same (iter, ws, seed) shape as the canonical Mixed 10-run, but shorter.
|
|
#
|
|
# Phase 68 Update: Diversify WS and seeds to reduce overfitting.
|
|
# - Mixed WS: Added 100, 256, 512, 1024 to existing 400 (5 patterns total).
|
|
# - Tiny hot: Added seed variants 60001, 60002 to 60000 (3 seeds total).
|
|
PGO_WORKLOADS=(
|
|
# Mixed: run via cleanenv to match benchmark presets (prevents PGO mismatch).
|
|
# Keep runs small; collector enforces per-workload timeout.
|
|
# Expanded WS range: 100, 256, 400, 512, 1024 (was: 128, 400, 800)
