* Avoid hashing the operator type in the GraphViewer priority node check unless the string has a chance of matching. Below are perf numbers from a test that loads 16 models multiple times. I was checking that some unrelated changes didn't have unexpected perf cost and found the PriorityNodeCompare overwhelmed any contribution the other changes were making. *Before* CPU Time:74.678s CPU Time for relevant Top Hotspots std::_Hash_array_representation<char> 20.834s onnxruntime::PriorityNodeCompare::IsHighPri 7.589s onnxruntime::Graph::KahnsTopologicalSort 4.487s *After* CPU Time:47.103s CPU Time for relevant Top Hotspots onnxruntime::Graph::KahnsTopologicalSort 4.465s onnxruntime::PriorityNodeCompare::IsHighPri 2.873s |

ONNX Runtime is a cross-platform inference and training machine-learning accelerator.
ONNX Runtime inference can enable faster customer experiences and lower costs, supporting models from deep learning frameworks such as PyTorch and TensorFlow/Keras as well as classical machine learning libraries such as scikit-learn, LightGBM, XGBoost, etc. ONNX Runtime is compatible with different hardware, drivers, and operating systems, and provides optimal performance by leveraging hardware accelerators where applicable alongside graph optimizations and transforms.
