xianyujie commented on issue #15108: The test time of the model on GPU is normal, but the test time on CPU is very long. URL: https://github.com/apache/incubator-mxnet/issues/15108#issuecomment-498944552 @pengzhao-intel I think you misunderstood the result. Take a look at the following results, different inputs have a great influence on the operation time of convolution layer, What could be the reason for this result? **same image as input, get the output(pre_output1,pre_output2) from stage1_unit1_relu1 layer of the two models.Then test the time of Conv layer, pre_output1 as the input of my model, pre_output2 as the input of original model.** (my_model: 0.075896, original model: 0.006333) **The pre_output1 as the input of the two models, test the time of Conv layer** (my_model: 0.072311, original model: 0.072548) **The pre_output2 as the input of the two models, test the time of Conv layer** (my_model: 0.0055, original model: 0.005653)
