Description

This PR introduces a comprehensive benchmark testing framework with three core components:

1. torch_infer.py - PyTorch model inference performance testing
2. paddle_infer.py - PaddlePaddle model inference benchmarking
3. api_serve.py - API service performance testing

The framework provides standardized metrics collection including:

• Inference throughput (tokens/second)
• Generated token length analysis
• Token generation time statistics

Execution Scripts​​
Corresponding launch scripts are available in the scripts/ directory:

1. api_serve.sh - API service testing
2. paddle_infer.sh - PaddlePaddle benchmark
3. torch_infer.sh - PyTorch benchmark
