openVino - high session creation times

[deischi]

When using the openVino execution provider, I notice a very nice speed up compared to the default CPU execution provider. Great.
But I also see a much longer session creation time.

See those numbers from onnxruntime_perf_test:

CPU: Average inference time cost: 76.676 ms
OpenVino: Average inference time cost: 37.3379 ms

CPU: Session creation time cost: 0.0344839 s
OpenVino: Session creation time cost: 1.92375 s

Are those high session creation times expected?
Are there ways to reduce that time?

Thanks
