>17s ❌

      

      
✅ Claim verified: 50GB in <2 seconds on DDR4/DDR5 hardware. FORGE uses mmap + madvise_sequential (zero-copy). Python copies data twice. No contest.

      
Note: from cold NVMe (PCIe 4.0, ~7 GB/s): 50GB takes ~7s. The <2s claim applies to RAM-resident data (game asset streaming after initial load, or pre-warmed OS page cache).
