Description Seng Phung Lu CLA 2007-05-16 15:39:01 EDT 
Build ID: I200705111421

Steps To Reproduce:
While building a large workspace, I profiled org.eclipse.jst.j2ee.componentcore.util.EARVirtualComponent.getHardReferences() being called over 1,200 times (Note: this snapshot was taken at only 5% workspace build completion).  Within this method, checking a project's type is called 84,000 times. 

ie. J2EEProjectUtilities.isDynamicWebProject, J2EEProjectUtilities.isStaticWebProject, J2EEProjectUtilities.isJCAProject, J2EEProjectUtilities.isUtilityProject

Using the above methods does not scale well in this case.  Pls consider caching and/or improving the utility method's response time.



More information:
I have attached an img showing the call stack as well as the time and invocation counts for each method.
