gradio: The file uploading speed is way slower in Gradio 4 than in Gradio 3

Describe the bug

I am using gr.File(…) to upload DXF file as input for the next step. But I noticed that the uploading speed is super slow when I upgrade my gradio 3.34.0 to gradio 4.4.0/4.5.0. To upload a file around 300KB, the previous uploading time is <100ms, but now it is around 5-10 seconds.

Any clue to explain this or solve this?
