text: Title: [Feature] Add QWQ’s Benchmark Code for Inference Performance Evaluation
  Body: ### Checklist

  ### Motivation
  
  Reasoning models typically generate many tokens, making them suitable for evaluating the performance of inference frameworks. As a result, they serve as a valuable benchmark for performance comparisons.
  
  QWQ has open-sourced its benchmarking code, which could be integrated into the Sglang benchmark suite. This addition would help users compare the performance of different inference frameworks more conveniently when running inference models.
  
  Would it be possible to add support for this benchmark in Sglang?
  
  Reference:
  	•	[QWQ’s benchmark code](https://github.com/QwenLM/QwQ/tree/main/eval)
  
  Potential Benefits:
  	•	Provides a standardized way to evaluate reasoning performance.
  	•	Helps users compare different inference frameworks more effectively.
  	•	Enhances Sglang’s benchmarking capabilities.
