@jackfengibm Could you clarify why you chose 1 as the default here? We think this might have to be much higher to represent a typical value for a production system.

Also, we think this should set in the default [dea.yml](https://github.com/cloudfoundry/dea_ng/blob/master/config/dea.yml) like `memory_overcommit_factor` for instance. Similarly, it should also be in [config.rb](https://github.com/cloudfoundry/dea_ng/blob/master/lib/dea/config.rb).

Once this has been changed, a corresponding change in cf-release (e.g. [templates/dea.yml.erb](https://github.com/cloudfoundry/cf-release/blob/master/jobs/dea_next/templates/dea.yml.erb)) is needed to make this property configurable via a deployment manifest. Search for `memory_overcommit_factor` in cf-release for an example of all the places that likely need to be updated.
