 To maximize the performance of Dinamica EGO execution, follow the guidelines below:
-  * Make sure the GUI option "Tools => Options | Advanced | Automatically detect the number of processors available" is selected. If you are running your models using the Console Launcher Tool, make sure the "Processors" option for each model is set to 0.
+  * Make sure the GUI option "Tools => Options | Advanced | Automatically detect the number of processors available" is selected. If you are running your models using the command line, make sure the "-processor" option for each model is set to 0.
-  * 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. 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 Vista/7 32-bit SO.//
+  * Set the memory management option ("Tools" => "Options" | "Advanced") to "Balanced" or "Aggressive". If your are using the command line tool, you will have to use the option "-memory-allocation-policy" with values 1 or 4, respectively;
-  * Make sure the "[[plugins_4|Enhancement Plugin for Dinamica EGO]]" extension is installed and the GUI option "Tools => Options | Advanced | Disable compilation of native expressions" is unchecked. On the Console Launcher, uncheck "Disable expression compilation".
+  * Make sure the "[[plugins_4|Enhancement Plugin for Dinamica EGO]]" extension is installed and the GUI option "Tools => Options | Advanced | Disable compilation of native expressions" is unchecked.
-  * Make sure the GUI option "Tools => Options | System | Message log level" is set to Result. //This is really important when running models with lots of loop containers like [[Repeat]], [[While]], [[For]] etc//.
+  * Make sure the GUI option "Tools => Options | System | Message log level" is set to Result. //This helps when running models with lots of loop containers like [[Repeat]], [[While]], [[For]] etc//.
   * 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.

 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.
-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.
