Subject Re: [Discuss] Specifying CPU and Memory in Docker Cartridges
Date Thu, 21 May 2015 05:20:56 GMT
Thanks for the feedback Raj! I think you made a good point, the defaults
should be set to zero to make them none restricted.
What I observed is that when we set these values the containers get more
time to start.

Thanks
