5. Benchmark

​
5.1 Speed Benchmark

Test Environment:
  • Hardware: AMD MI300X GPU (1x)
  • Model: DeepSeek-OCR
  • Tensor Parallelism: 1
  • sglang version: 0.5.7
We use SGLang’s built-in benchmarking tool to conduct performance evaluation on the ShareGPT_Vicuna_unfiltered dataset. This dataset contains real conversation data and can better reflect performance in actual use scenarios. To simulate real-world usage patterns, we configure each request with 1024 input tokens and 1024 output tokens, representing typical medium-length conversations with detailed responses.
