   I met the same problem, I have a project with dilation convolution (resnet backbone). If I use a mxnet1.3.1-cu80 (pip install), the speed is 0.18~0.19s one iter. However, when I switch to mxnet1.4.0-cute80(pip install), the speed drop to 0.19~0.20s one iter. The speed drop slightly, I confused with this problem.
   OS: Ubuntu 16.04
   Driver: 384.130
   CUDA: 8.0
   cudnn: maybe 7.4.1 or 6.0.21
