+#### 1. Prepare TensorRT-LLM extra configs
+```bash
+cat >./extra-llm-api-config.yml <<EOF
+stream_interval: 2
+cuda_graph_config:
+  max_batch_size: 1024
+  enable_padding: true
+EOF
+```
+Explanation:
+- `stream_interval`: The iteration interval to create responses under the streaming mode.
+- `cuda_graph_config`: CUDA Graph config.
+  - `max_batch_size`: Max CUDA graph batch size to capture.
+  - `enable_padding`: Whether to enable CUDA graph padding.

+#### 3. Run performance benchmark
+TensorRT-LLM provides a benchmark tool to benchmark trtllm-serve
+Prepare a new terminal and run `benchmark_serving`
+```bash
