[jboss-jira] [JBoss JIRA] Created: (EJBTHREE-1260) Performance issue with EjbLinkDemandMetaData
Performance issue with EjbLinkDemandMetaData
--------------------------------------------
Key: EJBTHREE-1260
URL: http://jira.jboss.com/jira/browse/EJBTHREE-1260
Project: EJB 3.0
Issue Type: Bug
Components: core
Affects Versions: AS 5.0.0.Beta4
Reporter: Guy Coleman
We have an application with about 200 EJB3 SLSB and MDBs, 120 EJB2 entity beans and a few
web apps.
This takes about 1-2 minutes to start up with JBoss 4.2.2.GA. With 5.0.0.Beta4 this jumps
to around 20-30 minutes. Some thread dumps show that it's spending most of its time
here:

Patching EjbLinkDemandMetaData to avoid creating ObjectNames for names that are obviously
invalid speed this up considerably: the startup time is then about 5 minutes, though It
still seems to spend a lot of time looping in that EjbLinkDemandDependencyItem .resolve
