Developer Zach Mueller benchmarked GLM-5.3-Flash NVFP4 with NVIDIA AI Perf on 4x RTX 6000 Max-Q, sweeping concurrency from 1 to 32.
Key finding: scaling beyond 8 concurrent requests yields no per-user token throughput gain while TTFT keeps rising. He published a Pareto interactivity chart as a practical guide for local deployment sizing.
