Identifying and Mitigating Systemic Measurement Bias in Production LLM Inference Benchmarks

Researchers have identified significant measurement bias in production LLM benchmarking tools, where single-process architectures and Python's Global Interpreter Lock artificially inflate latency metrics at scale. The study proposes a multi-process evaluation framework and a new normalized metric (NTPOT) to accurately measure LLM serving performance under production-level concurrency.
