Docker on a linux VM, performances? : <p>I would like to know what Docker on VM implies regarding the performances, will I have issue ? </p>

<p>To me, adding a "layer" would decrease the performances. Is it right or wrong and most importantly, why ?</p>

<p>I want to be able to know what is the best way to deal with new projects when containers are on the line. </p>

<p>Thanks in advance :)</p>
