Tips to make Eclipse IDE faster

1. Update Eclipse: Make sure you are using the latest version of Eclipse IDE. Newer versions often include performance improvements and bug fixes.
2. Increase Memory Allocation:Eclipse’s performance can improve significantly by increasing the amount of memory allocated to it.
   • Locate the eclipse.ini file in your Eclipse installation directory.
   • Open eclipse.ini in a text editor.
   • Find the line starting with -Xmx (e.g., -Xmx1024m).
   • Increase the value to allocate more memory. For example, change -Xmx1024m to -Xmx2048m to allocate 2GB of memory.
   • Save the file and restart Eclipse for the changes to take effect.
3. Optimize Workspace Settings:Eclipse stores various settings and temporary files in your workspace. You can optimize the workspace settings to improve performance by disabling unnecessary validations, enabling selective project building, and configuring resource filters to exclude unnecessary files.
   • In Eclipse, go to Window > Preferences.
   • Navigate to General > Workspace.
   • Uncheck “Build automatically” if it’s enabled.
   • Disable unnecessary validations by navigating to Validation and deselecting unnecessary validators.
   • Enable selective project building by navigating to General > Project Builders and deselecting unnecessary builders.
   • Configure resource filters to exclude unnecessary files or directories by navigating to General > Editors > File Associations, selecting the file type, and adding exclusion patterns.
   • Click Apply and OK to save the changes.
4. Disable Unnecessary Plugins:Eclipse allows you to install numerous plugins, but having too many active plugins can slow down the IDE. Disable any plugins that you don’t use regularly to improve performance. You can manage plugins from the Eclipse preferences menu.
   • In Eclipse, go to Help > Eclipse Marketplace.
   • Search for installed plugins and disable any that you don’t use frequently.
   • Alternatively, go to Window > Preferences > Install/Update > Available Software Sites and disable update sites for plugins you don’t use.
   • Click Apply and OK to save the changes.
5. Use Lightweight Themes:Eclipse themes with many visual effects and gradients can consume additional system resources. Consider using lightweight themes that have minimal visual effects to improve performance.
   • In Eclipse, go to Window > Preferences.
   • Navigate to General > Appearance.
   • Select a lightweight theme or customize the current theme to reduce visual effects.
   • Click Apply and OK to save the changes.
6. Enable Workspace Auto-Save:Enabling workspace auto-save can help reduce the frequency of manual saves, especially for large projects, and improve overall responsiveness.
   • In Eclipse, go to Window > Preferences.
   • Navigate to General > Editors > Autosave.
   • Enable Autosave and adjust the Autosave delay as per your preference.
   • Click Apply and OK to save the changes.
7. Close Unnecessary Views and Editors:Close any views or editors that you are not using at the moment. Each open view or editor consumes system resources, and reducing their number can improve performance.
   • Close any views or editors that you are not currently using by clicking on the close button (usually ‘x’) on their tabs.
   • You can also use the Window menu to close specific views or editors.
   • Alternatively, use the Quick Access feature (Ctrl+3) to quickly switch between views and editors instead of keeping them open simultaneously.
8. Regularly Clean and Rebuild Projects:Performing a clean build on your projects periodically can help resolve any inconsistencies and improve overall performance.
   • Right-click on the project in the Project Explorer view.
   • Select Clean Project to clean the project.
   • After cleaning, right-click on the project again and select Build Project to rebuild it.

By following these steps, you should be able to optimize the performance of Eclipse IDE and enjoy a faster development experience.
