I can reproduce the difference in perforamce between CD CentOS setup and CI
CentOS setup locally.
For CD setup, I use
```
rm -rf lib build; python ci/build.py --cache-intermediate --platform
centos7_cpu /work/runtime_functions.sh build_static_libmxnet cpu
```
and for CI setup I use
```
rm -rf lib build; ci/build.py --docker-registry mxnetci --platform
centos7_cpu --docker-build-retries 3 --shm-size 500m /work/runtime_functions.sh
build_centos7_cpu
```
In both cases I have modified the cmake file to remove intgemm:
