If your machine has multiple cores, and your OS is Linux, you can run EMS in clustered mode by setting the EMS configuration file, config.lua, as follows:
1) daemon=true to enable daemon mode.
2) instancesCount=-1 to get the maximum number of edge instances based on the number of cores on your CPU. Setting it to a positive number limits the number of edge instances to that number (within the number of cores available). An origin instance of EMS will exist in addition the edge instance(s).
To disable clustered mode, set daemon=false, or set instancesCount=0. In this case, only an origin instance of EMS will run.
