 ## Performance Benchmark
-We benchmarked the performance of SGLang Diffusion against a popular open-source baseline Huggingface Diffuser.
-As benchmarked in the chart at the top of this post, SGLang Diffusion delivers state-of-the-art performance, significantly accelerating both image and video generation.
+As shown in the chart at the top of this post, we compared the performance of SGLang Diffusion:
+  - Against a popular open-source baseline, Hugging Face Diffusers. SGLang Diffusion delivers state-of-the-art performance, significantly accelerating both image and video generation.
+  - Under different parallelism setups. Both CFG-Parallel and USP deliver significant speedups compared to the single-GPU setup.
