MCR CACHE ROOT
The MCR_CACHE_ROOT is an environment variable in Linux that can be used to speed up the use of the standalone version of Dynamo.
The value of the MCR_CACHE_ROOT tells the MCR libraries a location of the filesystem where some elements can be extracted (once) for later use during runtime. Unpacking to disk is a slow operation, so that you want to use a location that is on a fast partition of your file share. For instance, when working on a networked location, (i.e., your HOME directory is not in your desktop), you probably want to set the variable MCR_CACHE_ROOT to point to a local partition on your machine, rather than letting the system choose a remote location inside the network.
It is specially useful if you make this variable point to a file share corresponding to SSD memory.
