Nice catch! This is what happens when we're all on little sleep. For now we need all contributors to have a CLA on file. I didn't find one for you so I just need to make sure that you've done that at https://developers.facebook.com/opensource/cla. Let me know when it's done and I'll merge this in. Thanks a lot! |

…ok#9) v2 measured wall-clock time with simulated I/O, which hid the CPU cost. Throughput is limited by CPU, not I/O. Under concurrent load on a single Node.js thread: c=25, 226 products: - Fizz only: 526 req/s, p99=49ms, heap +72MB - Full pipeline: 102 req/s, p99=342ms, heap +282MB - Drop: 5.2x throughput, 7.0x p99, +210MB heap The overhead worsens under load (4x at c=1 → 5.9x at c=50) because the 349KB wire format buffer per request creates GC pressure that compounds with concurrency. This directly explains the 400→40 rps drop in real deployments: React-level 3-6x × framework overhead 1.5-2x ≈ 10x. Recommendation: proceed with fused renderer.
