Subject [jira] Commented: (MYFACES-2780) MyFaces performance improvements for production
Date Wed, 07 Jul 2010 10:29:50 GMT


Martin Marinschek commented on MYFACES-2780:

Well, I am ok with lazy loading if it does not change the request times, also not the ones
for the first request. How much loading do you defer - is it changing the time needed for
processing a request?

In any case, I guess this should be configurable.

best regards,

> Several fixes to enhance startup memory footprint and runtime performance taking advantage
of ProjectStage.
> -lazy loading of validators, converters, behaviors,components - can have a substantial
impact on startup footprint in applications with multiple or very large widget libraries.
> Turn off some updating of resources for ProjectStage=Production by default (can always
override using javax.faces.FACELETS_REFRESH_PERIOD)
> -change default facelets refresh interval to -1 when projectStage is production.  This
by itself gains a 60% improvement in throughput.
> -disable reloading of web.xml and faces-config after the first load.  
> -store a map to cache Class to listenerFor and resourceDependency annotations when in
