Hi The helloworld app I'm trying does not have any component libs installed.
Even with more libs in your classpath, if GAEFacesConfigurationMerger hack is working, no xml or annotation scanning is done. Looking in deep for ways how to improve this, probably it is possible to create a custom ServiceProviderFinder to speed up SPI and avoid calls to Classpath.getResources() that could involve scan the whole classpath (including unnecessary jar files) without need. regards, Leonardo Uribe 2012/6/7 lucio piccoli <lu...@asteriski.com>: > hi leonardo > > i dont know how your app is starting myfaces in 3secs. > how many faces component lib have u installed? > > i have tomahawk, richfaces and onload installed. > > with these i see a 10 sec elapsed time. > > -lp > > On 7 June 2012 17:37, Leonardo Uribe <lu4...@gmail.com> wrote: > >> Hi Lucio >> >> In my test app I have: >> >> <context-param> >> <param-name>org.apache.myfaces.GAE_JSF_JAR_FILES</param-name> >> <param-value>none</param-value> >> </context-param> >> >> <context-param> >> >> <param-name>org.apache.myfaces.GAE_JSF_ANNOTATIONS_JAR_FILES</param-name> >> <param-value>none</param-value> >> </context-param> >> >> Disabling annotation scanning and faces-config.xml or .taglib.xml >> finding in jar files. >> >> If I use the hack proposed before using GAEFacesConfigurationMerger >> (store config into >> datastore to retrieve it later) I have around 7 seconds.
