[Performance] CreateSession takes very long time to load .onnx file when working with FileFuzzer tool

[chenyihong0504]

Describe the issue

We hit this perf issue when doing Fuzz testing using FileFuzzer tool for Speech Runtime, check below for what we got. Normally it is expected that scenario 1 is faster than scenario 2, but it is too slow for CreateSession() function which is blocking us to do the fuzz testing.

Scenario 1: E2E decoding scenario using Command Prompt Windows => Took about 4 secs in total, CreateSession() for big encoder.quantqint8.onnx file (87.8MB) took less than 2 secs, total time for 4 .onnx files is around 2 secs.
Scenario 2: E2E decoding scenario through FileFuzzer tool => Took about 67 secs in total, CreateSession() for big encoder.quantqint8.onnx file (87.8MB) took about 51 secs, total time for 4 .onnx files is about 56 secs.

Notes: we verified with the latest version [v1.20.1], this issue also repro.

To reproduce

Here is a local setup to repro the issue using en-US model:
\MixedRealityFS\PRIVATE\Speech\speechshare\USR\yihche\4ONNXRuntimeComponent\ReproFuzzBug11045

1. Copy ReproFuzzBug11045 to local machine e.g. at E:\FuzzTesting
2. Install FileFuzzer 3.0 with MSI files at Software\FileFuzzer 3.0\amd64
   2.1 Install FCL.msi first
   2.2 Then install FileFuzzer.msi
   Default installation path is at C:\Program Files\Microsoft\FileFuzzer
3. Modify FileFuzzer_ConfigFile.xml for , and to matching your local setup path.
   Here are the examples:
   E:\FuzzTesting\ReproFuzzBug11045\audio\en-US
   E:\FuzzTesting\ReproFuzzBug11045\output-Fuzzer
   E:\FuzzTesting\ReproFuzzBug11045\ReproBug11045_SlowIssue.bat
4. Open FileFuzzer UI as administrator from C:\Program Files\Microsoft\FileFuzzer\FileFuzzerConfig.exe
   4.1 Click "Load Settings" and select FileFuzzer_ConfigFile.xml
   4.2 Click "Start" button.
5. Check testing results in path

Urgency

It is a blocking issue for us to do Fuzz testing, and we have to reduce seed and iteration numbers as temporary workaround.
