[richfaces-issues] [JBoss JIRA] Updated: (RF-11000) Hit miss for class loader cost performance problem in Richfaces 4.1.0.

[ https://issues.jboss.org/browse/RF-11000?page=com.atlassian.jira.plugin.s... ] Brian Leathem updated RF-11000: ------------------------------- Description: There are scenarios when resources are retrieved during no partial request processing: # JSF html renderer (such as ScriptRenderer from faces) require to know resources names to include them to html/head, # Resources content request. We have two types of resources: dynamic and static. Predefined dynamic resources (such as StateHolderResource) are read using class loader as they are java classes. Static resources are kept in resources folder as part of richfaces release jars (jquery.js, richfaces.js, etc). There is a special case with compiled css that is consider as dynamic resources but is not important in our case. The problem appears when we try to load static resources using dynamic loader. This make unnecessary lookup in java class loader space which cost time and of course we miss the call as static resources not exists there. Statistics that shows class loader hits for every richfaces/ajax4jsf no partial request that will be eliminated after patch: {code} Resource::jquery.js ::loading::timens:: 558000 ns::timems::0.558 ms::all::1.561496 sec Resource::richfaces.js ::loading::timens:: 490000 ns::timems::0.490 ms::all::1.561986 sec Resource::richfaces-base-component.js::loading::timens:: 593000 ns::timems::0.593 ms::all::1.563672 sec Resource::richfaces-queue.js ::loading::timens:: 672000 ns::timems::0.672 ms::all::1.564350 sec Resource::richfaces-event.js ::loading::timens::3292000 ns::timems::3.292 ms::all::1.569386 sec {code} was: There are scenarios when resources are retrieved during no partial request processing: 1) JSF html renderer (such as ScriptRenderer from faces) require to know resources names to include them to html/head, 2) Resources content request.
