, hopefully in the next beta.


Performance improvements for the command line

We have done some performance work on work to improve the performance of the command line to reduce the , less memory (RAM) is now used during a run and to speed up runs run time in the command line.

The command line now has additional options for results saving:


There are three modes currently available (4. with another coming soon):

  1. noOutput - This improves performance when using automatic exporting tooks tools such as Scenario Options: Simulation results or Simulation Log which automatically exports results after each run to a specific location. 
  2. serverNamedFormat - This mode saves from the server, rather than transferring data back to the client when in client-server mode. This is also now the default for a single computer run, meaning performance is improved by not transferring the data.
  3. clientNamedFormat - (default for client-server mode). The data is transferred back to the client and saved (current behaviour).
  4. Coming soon: serverStreamedFormat - this will be available with results streaming in the next beta release.
