How to improve performance of jsf myfaces based application ?

Some tips that I have collected so far

Trinidad

  • Set following init parameters to false in web.xml
    • org.apache.myfaces.trinidad.DEBUG_JAVASCRIPT
    • org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION
    • org.apache.myfaces.trinidad.CHECK_FILE_MODIFICATION
  • use client-side state saving
  • clear pageflow context map when not in use

Myfaces

  • Set following init parameters to false in web.xml
    • org.apache.myfaces.COMPRESS_STATE_IN_SESSION
    • org.apache.myfaces.SERIALIZE_STATE_IN_SESSION
    • org.apache.myfaces.PRETTY_HTML
    • org.apache.myfaces.VALIDATE
  • Reduce value of org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION from init param (default is 20)

facelets

  • Set following init parameters to false in web.xml
    • facelets.DEVELOPMENT
    • facelets.SKIP_COMMENTS
  • set facelets.BUFFER_SIZE and com.sun.faces.responseBufferSize to large value like 10000000
  • set facelets.REFRESH_PERIOD to -1

Is there anything else to add to this ?

Moving to Stateless JSF would offer a great performance boost. Now it's possible to use JSF entirely stateless. See this blog & this issue. A payoff is that you can't create views dynamically (e.g. by binding, JSTL tags, etc), nor manipulate it after creation.

A Stateless JSF operation mode would be incredibly useful for high-load applications and architectures:

This has previously been suggested by Jacob: http://weblogs.java.net/blog/jhook/archive/2006/01/experiment_goin.html

This would help JSF ditch the stigma of "slow and memory hog," and help keep up with current tech trends (stateless architectures.)

Came across the following link. Will be useful if you're using ADF based (now MyFaces Trinidad) implementation.
