about
nx_dod_cache_gate.nx -- proves the SoA/ECS cache EXCEEDS vs AoS. System touches 2 of 8 fields over
1024 entities (8B fields, 64B lines). SoA streams 2 component arrays; AoS drags all 8 fields. Measured:
SoA uses 4x fewer cache lines (= F/A), advantage GROWS with field count, AoS utilization 25% vs 100%.
NEG-CONTROL: a system using ALL 8 fields -> SoA == AoS (PARITY), so the win is honest (selective access
only). license_tier: ORIGINAL expect_exit: 0
