 `torch.compile()` is a JIT compiler and JIT compilers generally have a startup cost. To reduce the warm up time, `TorchInductor` already makes use of caching in `/tmp/torchinductor_USERID` of your machine

+## C++ AOTInductor examples
+
+AOTInductor is the Ahead-of-time-compiler, a specialized version of `TorchInductor`, designed to process exported PyTorch models, optimize them, and produce shared libraries as well as other relevant artifacts. These compiled artifacts are specifically crafted for deployment in non-Python environments. You can find the AOTInductor C++ examples [here](../cpp/aot_inductor)
