Joke09 commented on issue #13545: For inference, I have the same problem. The client send jpg to server, then the server use cv2 to do resize. When put the image data into the mx.nd.array, it's very slow. And the Utilization of GPU is low too. How to solve it? Thank you!

It works, But not much. Before: data = [mx.nd.array(im_arrays), mx.nd.array(im_infos)] The shape of im_arrays is [8,3,896,1024]. It take 104ms. After: data = [mx.nd.array(im_arrays, ctx=mx.gpu(1)), mx.nd.array(im_infos)] It take 68ms. I think it's not fast enough.
