How to reduce page load time for CQ5 Pages?

Hi,

How to reduce page load time for CQ5 Pages?explain?

[Runal_Trivedi]

You can do following to reduce your page load time:

• For Initial analysis of time load for a page, have CQ OOTB Timing component added to the page as it reports the time taken by each component to load and a page.
  • More on how to use timing component - http://www.wemblog.com/2014/05/how-to-find-component-load-time-on-page.html
  • This will help you to identify components that takes more time to load which you can then fix or live with.
• Cache as much content as possible (this would be done with the help of dispatcher)
  • Carefully invalidate the cache on content activation.
  • Dispatcher and its configuration details - http://docs.adobe.com/docs/en/dispatcher.html
• If you components are dependent on webservice or other layers apart from CQ to process and display content then if possible, have them as REST calls done via AJAX, this would reduce server side rendering time.
• If at all you are going to write sling filters then as they intercept every request define the entry condition before you start processing your request in filters and exit from it as soon as possible.
• Above point applies to Event listeners as well.
  • Use filters and listeners only when needed as they may cause lower down your server performance.
• To enhance the performance of server there are certain OSGI configuration suggested at http://docs.adobe.com/docs/en/cq/current/deploying/osgi_configuration_settings.html, follow what suits you (at least you should disable debug filter, and Minify the client libs)

Thanks

Along with runal suggestion make sure

1. All recommended hotfix/sp is installed.
2. Performance optimization & tunning is done

My preferred approaches:

• Use the "recent requests" tab in your OSGI console to identify components and pages, which take a long time.
• Take care of JCR queries. Try to get them out of the direct rendering path of a page.
• Instead of blindly doing JCR queries you could think of tree iteration, which might be faster sometimes.

I know, we have to go to the Felix Console and click on “Configuration”. The Bundle to configure is the “Apache Sling Main Servlet” (PID org.apache.sling.engine.impl.SlingMainServlet) and the property, as you may guess “Number of Requests to Record” (sling.max.record.requests). Set it to your desired value.

Question:  but after the configuration how do we track and debug the requests.
