 ## Inference Performance
 
 
-This model achieves up to 1.4x speedup in single-stream deployment and up to 1.8x speedup in multi-stream asynchronous deployment, depending on hardware and use-case scenario.
+This model achieves up to 1.4x speedup in single-stream deployment and up to 3.0x speedup in multi-stream asynchronous deployment, depending on hardware and use-case scenario.
 The following performance benchmarks were conducted with [vLLM](https://docs.vllm.ai/en/latest/) version 0.6.7.2, and [GuideLLM](https://github.com/neuralmagic/guidellm).
