What do to increase the performance?

General performance issues are noticeable when using logi.CAD 3.

Cause: Windows 10 Defender is scanning the JAR files included in logi.CAD 3 and significantly slows logi.CAD 3.

Additional information: logi.CAD 3 is based on a release of the Eclipse Foundation (see "Elements of the development environment" for details). The problem regarding the Windows 10 Defender has been reported as an Eclipse issue under: https://bugs.eclipse.org/bugs/show_bug.cgi?id=548443

Workaround: Add the logi.CAD 3 root folders to Windows 10 Defender's exclusion list:

1. Open Windows 10 settings.

2. Search for Virus & threat protection and open it.

3. Now click on Manage settings under Virus & threat protection settings section.

4. Now click Add or remove exclusions under Exclusions section.

5. Now click Add an exclusion then select Folder.

6. Point to the respective logi.CAD 3 root folder and press Select Folder.
   The root logi.CAD 3 root folder are:

   1. the installation folder (= the folder to which logi.CAD 3 has been installed)

   2. the folder for the workspace (= the folder for the workspace that has been specified when starting logi.CAD 3) and

   3. the folder(s) containing the logi.CAD 3 →projects

The project actions cause some time of waiting .

See "The project actions take a long time."

Windows security alerts appear when starting logi.CAD 3 or loading the application.

See"The Windows Firewall has blocked features of this program."

Saving some editors takes a long time. These editors contain many private elements .

By using the configuration variable lc3.removeLocalVariablesFromIndexer you can increase the performance when saving editors. This configuration variable has an effect in particular if you have →Funktionsbausteine with private →variables and private →function block instances in your application.

With the value TRUE for this configuration variable, function blocks with private variables and private function block instances are not considered when updating the application. This application update is triggered automatically when the editor is saved.

Please observe that private variables and private function block instances are those elements declared with the PRIVATE keyword in the function block. If the default behavior is changed to PRIVATE, they are also those elements declared without a keyword for visibility. Details: See "Declaration of internal variables in ST" and "Declaration of function block instances in ST".

The ST-editor reacts sluggishly to actions

See"ST-editor reacts sluggishly."

Saving an FBD-editor with many pages takes a long time .

See"Can I increase the performance when saving the FBD-editor?".

logi.CAD 3 is not started at all, an application cannot be build/loaded.

Cause: Your virus scanner prevents or delays the start or the building/loading of the application.
See "Development environment cannot be started. There is no error message." and "Cannot build or load application"
