Eclipse 4 ui slow. CSS Engine called too often (Windows)
If you're experiencing slow performance in Eclipse 4 UI on Windows, particularly related to the CSS engine being called too often, you can try the following steps to improve the performance:
Disable CSS Styling: If you're not using any custom CSS styling in Eclipse, you can disable the CSS engine altogether. To do this, go to Window -> Preferences -> General -> Appearance and uncheck the "Enable CSS styling" option.
Reduce Refresh Rate: You can reduce the refresh rate of the CSS engine to minimize the number of times it gets called. Go to Window -> Preferences -> General -> Appearance -> Colors and Fonts and adjust the "Refresh rate" slider to a lower value.
Disable Animations: If Eclipse is using animated transitions that are impacting performance, you can disable them. Go to Window -> Preferences -> General -> Appearance and uncheck the "Enable animations" option.
Increase Memory Allocation: Eclipse may benefit from increased memory allocation. You can adjust the memory settings in the eclipse.ini file. Look for the -Xms and -Xmx parameters and increase the values to allocate more memory to Eclipse. For example, you can set -Xms512m -Xmx1024m to allocate 512MB as the initial heap size and 1024MB as the maximum heap size.
Update Eclipse and Plugins: Make sure you're using the latest version of Eclipse and any installed plugins. Updates may include performance improvements and bug fixes.
Disable Unnecessary Plugins: If you have any plugins installed that you're not using, consider disabling them to reduce the overall resource usage.
Optimize Workspace: Clean up your workspace by removing unnecessary projects, closing unused editors, and minimizing the number of open files.
Update Graphics Drivers: Ensure that your graphics drivers are up to date. Outdated or incompatible graphics drivers can sometimes cause performance issues.
These steps should help improve the performance of Eclipse 4 UI on Windows. However, if you're still experiencing significant performance issues, you may need to consider using alternative IDEs or exploring additional performance tuning options specific to your environment.
