More slower use TVM than MXNet when I use batch forward


#1

I run the imagenet classify model (resnet34) in gpu mode,

In tvm
the shape (1 x 3 x 224 x 224) cost 2.9ms each times , more faster then mxnet (3.5ms)

but the same mode, cost 17ms in shape (10 x 3 x 224 x 224) in TVM
and the mxnet cost 14ms in shape (10 x 3 x 224 x 224).

Is reasonable ?
