   @lanking520 this is my system info, i test Python 3.6.4 and Python 2.7.12 on ubuntu 16.04
and 14.04. 
   root@5360f6cad7ec:/# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
         8  Intel(R) Xeon(R) CPU E5-26xx v4
   root@5360f6cad7ec:/# getconf LONG_BIT
   64
   root@5360f6cad7ec:/# uname -a
   Linux 5360f6cad7ec 4.4.0-91-generic #114-Ubuntu SMP Tue Aug 8 11:56:56 UTC 2017 x86_64
x86_64 x86_64 GNU/Linux
   
   
   i found that when i run pip install mxnet (not mxnet-mkl)or  build form source(https://mxnet.incubator.apache.org/install/index.html?platform=Linux&language=Python&processor=CPU)
i can import mxnet normally ,but when i inference my model  ,it cost mort time(almost 4~ 5
times than mkl in my normal computers(which  can use mxnet-mkl)). 
   my cpu(Intel(R) Xeon(R) CPU E5-26xx v4) can't support mkl?
