Note

Our benchmark tests do not cover all possible optimization combinations. For example, we select the inference engine that performs best under its default configuration as the starting point for further tuning. This pruning approach yields a local optimum, which may not be the global optimum.
There are other optimization methods that depend on specific user scenarios, including max batch size, schedule configuration, extended KV cache, CUDA graph, etc. The conclusions in this document can serve as a starting point for more targeted optimizations.
The tests are conducted on specific hardware and software setups. Advances in the inference engine may lead to new conclusions.
Although using quantization may impact accuracy. FP8 quantization can achieve less than 1% accuracy drop for most models. See the evaluation results for more details. Therefore, it is highly recommended to use FP8 quantization for low-latency serving scenarios.
Speculative decoding can significantly reduce latency for low-concurrency requests. However, the acceleration effect may vary depending on the data distribution of different benchmark datasets and the choice of draft models. For example, the chosen draft model here is trained on English data, which may lead to suboptimal performance on other languages.

If there are any missing points or updates reflecting new changes, please let us know.

Experimental Setup

Model

Qwen/Qwen3.5-35B-A3B

Hardware

NVIDIA H200

Engine Version

vLLM v0.17.1
SGLang v0.5.9

Benchmark Method

This project uses GPUStack's one-click benchmark capability for serving workloads. The benchmark tests in this document were executed with that workflow.

GPUStack's benchmark implementation is built on top of guidellm via the wrapper project benchmark-runner.

GPUStack handles model deployment, benchmark job submission, and result collection for the benchmark configurations listed below.
