Is it normal for ResNet50-Faster-RCNN to be slower than VGG16 in Faster RCNN?

[yxchng]

My time for one forward pass in ResNet50-Faster-RCNN is 0.12s as compared to 0.06s in VGG16-Faster-RCNN.

I have merged the this caffe with the latest caffe.

I am using the official VGG16 prototxt for VGG16 and the following prototxt for ResNet 50:

name: "ResNet50"

input: "data"
input_shape {
  dim: 1
  dim: 3
  dim: 224
  dim: 224
}

input: "im_info"
input_shape {
  dim: 1
  dim: 3
}

[ujsyehao]

hi, you mentioned: 0.06s in VGG16-Faster-RCNN. but I test about 0.1 s use ./tools/demo.py , How do you measure the forward calculation?

[yxchng]

@ujsyehao I think we are probably just using different GPU. I am using GTX 1080 Ti.

[ujsyehao]

e, how do you measure the forward calculation time? you just run demo.py and get the result?

[yxchng]

@ujsyehao Yes. What GPU do you use?

[ujsyehao]

I use GTX 1070ti, but according to my investigation, py-faster-RCNN fps on k40 should be 4.5 fps, then our speed is much faster than 4.5
