2.3.3. Configuration of the plugin

The configuration of available RAM is recommended in order to reduce the processing time. From the SCP menu select settings_tool Settings > Processing .


In the Settings, set the Available RAM (MB) to a value that should be half of the system RAM. For instance, if your system has 2GB of RAM, set the value to 1024MB.
