Performance tuning in Liferay DXP involves optimizing various aspects of the platform to enhance its responsiveness and efficiency. Here are steps you can take for performance tuning in Liferay DXP:

1. Server Configuration:

  • Optimize the server configuration based on the expected load and usage patterns. Adjust parameters such as heap size, thread pools, and connection pools to match the requirements of your deployment.

2. Database Optimization:

  • Optimize the database configuration and performance. This includes indexing, query optimization, and database caching. Use the appropriate database for your workload and ensure that it is properly tuned.

3. Cache Configuration:

  • Utilize caching mechanisms effectively. Configure Liferay's in-built caching and leverage external caching solutions such as Ehcache or Redis. Caching can significantly reduce the load on the database and improve response times.

4. Content Delivery Network (CDN):

  • Implement a Content Delivery Network to cache static content closer to end-users, reducing latency and improving page load times.

5. Load Balancing:

  • Implement load balancing to distribute traffic across multiple server instances. This improves scalability and ensures that no single server becomes a bottleneck.

6. Minification and Compression:

  • Minify and compress static resources such as JavaScript and CSS files to reduce their size and improve download times.

7. Image Optimization:

  • Optimize images to reduce their file size without compromising quality. Use image compression tools and consider lazy loading for images that are not immediately visible.

8. Content Fragmentation:

  • Fragment large content into smaller parts to enable partial caching. This way, only the modified or new parts need to be reloaded, reducing the overall load on the system.

9. Monitoring and Profiling:

  • Use monitoring tools to track system performance. Profiling tools can help identify bottlenecks and areas that require optimization.

10. Database Connection Pooling:

- Ensure that you are using the latest version of Liferay DXP, as newer releases often include performance improvements and bug fixes.

16. Review and Optimize Custom Code:

vbnet
- Review custom code for any performance bottlenecks. Optimize customizations and third-party integrations to ensure they align with performance best practices.

17. Content Staging Optimization:

vbnet
- If using content staging, optimize its configuration to reduce the impact on performance. Adjust staging and publication intervals based on your content update frequency.

18. Regular Performance Testing:

css
- Conduct regular performance testing to identify potential issues before they impact users. Simulate various usage scenarios to ensure the platform can handle peak loads.

19. Documentation and Knowledge Sharing:

csharp
- Document the performance tuning configurations and share knowledge with the development and operations teams. This ensures that best practices are followed and adjustments can be made as needed.

20. Continuous Monitoring and Optimization:

sql
- Performance tuning is an ongoing process. Regularly monitor system performance, user feedback, and application behavior to identify areas for continuous improvement.

By systematically addressing these aspects, you can optimize the performance of Liferay DXP and provide a responsive and efficient digital experience for users. Always measure the impact of changes and adjustments to ensure they align with your performance objectives.


21. Continous code review by the experienced team members

22. Code review using tools like Sonar

23. Use of Monitoring tools like Dynatrace .

24. While performace analysis ..need to check following

a) Database call
b) Service calls
c) Code Logic response time
d) Elastic search
e) Heap Memory issues
d) Blocing threads issues
e) logging response time at each steps



There are also some changes you can make to your portal-ext.properties .

Set this property to true to load the theme’s merged CSS files for faster loading . By default it is set to false for easier debugging for development. You can also disable fast loading by setting the URL parameter css_fast_load to 0.

theme.css.fast.load=true

Set this property to true to load the combined JavaScript files from the property javascript.files into one compacted file for faster loading for production.

javascript.fast.load=true

Disable Servlet Filters which are not in use 


Liferay bundle comes with a number of servlet filters enabled and running. It is likely that for your installation, you don’t need them all. These filters intercept the HTTP request and do some processing on it before Liferay starts building the page .

You can disable servlet filters you’re not using by using your portal-ext.properties file. you can disable, by setting them to false.

example, if you are not using CAS OR NTLM ,  GZip filter, SSO filter, Sharepoint filter, NTLM Post filter, OpenSSO filter, etc  you can disable the respective filters .

  • com.liferay.portal.servlet.filters.sso.cas.CASFilter=false

The CAS filter is used to provide CAS based single sign on.

  • com.liferay.portal.servlet.filters.sso.ntlm.NtlmFilter=false

The NTLM filter is used to provide NTLM based single sign on.

  • com.liferay.portal.servlet.filters.sso.ntlm.NtlmPostFilter=false

The NTLM post filter is used to fix known issues with NTLM and ajax requests.

  • com.liferay.portal.servlet.filters.sso.opensso.OpenSSOFilter=false

The OpenSSO filter is used to provide OpenSSO based single sign on.

  • com.liferay.portal.servlet.filters.gzip.GZipFilter=false

If the user can unzip compressed HTTP content, the GZip filter will zip up the HTTP content before sending it to the user.

  • com.liferay.portal.servlet.filters.strip.StripFilter=false

The strip filter will remove blank lines from the outputted content.

  • com.liferay.portal.sharepoint.SharepointFilter=false

The Sharepoint filter allows users to access documents in the Document Library directly from Microsoft Office using the Sharepoint protocol.

  • com.liferay.portal.servlet.filters.layoutcache.LayoutCacheFilter=true

Enabling the layout cache filter will cache pages to speed up page rendering for guest users.

  • com.liferay.portal.servlet.filters.validhtml.ValidHtmlFilter=false
