 For this part, we are going to describe how to analyze torchinductor model performance.
 Firsly, we choose an eager model as a baseline. We set up a benchmark to compare
 the end to end performance between eager model and inductor model.

 We see inductor model spent more time than eager model, which does not meet our expectation.
