Jetpack 3.3 trt inference time is better than Jetpack 4.4 trt inference time

Here is the trtexec timings of a SSD based object detection model with jetpack 3.3 and jetpack 4.4 on TX1. Is it possible to get the timings of jetpack 3.3 with jetpack 4.4?

Hi,

Have you maximized the device performance first?

$ sudo nvpmodel -m 0
$ sudo jetson_clocks

The default clocks setting may be different on the JetPack4.3 and JetPack4.4.
Thanks.

Yes, already maximized the device performance.

Hi,

We want to reproduce this issue in our environment.
Would you mind to share the model file with us?

Thanks.

Here is the prototxt and a dummy caffemodel file for it. I can reproduce similar timings with this dummy weights.

Thanks.

We will reproduce this internally and update more info with you later.
