Docker: in memory file system
<p>I have a docker container which does alot of read/write to disk. I would like to test out what happens when my entire docker filesystem is in memory. I have seen some answers here that say it will not be a real performance improvement, but this is for testing. </p>

<p>The ideal solution I would like to test is sharing the common parts of each image and copy to your memory space when needed. </p>

<p>Each container files which are created during runtime should be in memory as well and separated. it shouldn't be more than 5GB fs in idle time and up to 7GB in processing time. </p>

<p>Simple solutions would duplicate all shared files (even those part of the OS you never use) for each container. </p>
