Inference time is slow

[dbAIStudio]

u2net_test.py It took more than 1 second to detect a single image of 2080, but you can see that it is 30 frames in the 1080 test, what is the reason for this?

[rdutta1999]

There could be multiple reasons for slow inference:

1. Slow CPU / GPU.
2. Not enough RAM leading to paging.
3. More parameters have been added (probably by changing the output shape), thus taking more computation time.
