 To maximize the performance of Dinamica EGO execution, follow the guidelines below: To maximize the performance of Dinamica EGO execution, follow the guidelines below:

If you are running your models using the Console Launcher Tool, make sure the "​Processors"​ option for each model is set to 0.
  
-  * If you have enough RAM memory, make sure the GUI option "Tools => Options | Advanced | Disable ​raster map swapping"​ is checked. On the Console Launcher Tool, check the Disable map swapping option. It will force EGO to use memory (not the hard disc) to do most calculations. It also allows the use of parallel algorithms by several operators. //Beware of [[faq#​question_p-2|memory limits]] whether you are using a Windows XP/Vista/7 32 bit SO.//+  * If you have enough RAM memory, make sure the GUI option "Tools => Options | Advanced | Disable ​the swapping ​of raster maps between hard drive and memory" is checked.

   * Avoid the definition of maps using [[cell type type|cell type]] "1 Bit Integer"​. This cell type saves memory, but it also has a huge negative impact in performance.   * Avoid the definition of maps using [[cell type type|cell type]] "1 Bit Integer"​.

 [[wp>​Zip_(file_format)|Zip]] files are useful to pack all files used by a model in a single archive. However, zipping all files does not increase the amount of data that Dinamica EGO can handle simultaneously. Behind the curtains, Dinamica unzips the files into a temporary folder and loads them from there. [[wp>​Zip_(file_format)|Zip]] files are useful to pack all files used by a model in a single archive.

If you use a file outside the zip archive, these files can be much bigger than that.
  
 To read a file located in a [[wp>​Zip_(file_format)|zip]] file, you have to use a [[Workdir]] container. Then, edit the [[Workdir]] and use the [[wp>​Zip_(file_format)|zip]] file name in the "​folder"​ input port. Place a file loader ([[Load Map]], [[Load Weights]] etc) inside the [[Workdir]] container. The file name mentioned in the file loader must match the name used by the file contained in the [[wp>​Zip_(file_format)|zip]] archive. To read a file located in a [[wp>​Zip_(file_format)|zip]] file, you have to use a [[Workdir]] container.

-The example ''​run_lucc_northern_mato_grosso/​run_roads_with_and_workdirs'',​ available as part of the Dinamica EGO installation,​ reads its inputs from a [[wp>​Zip_(file_format)|zip]] file. Check it out to see how that works in practice.
