Hi there,
I'm having some performance issues with the EJB plugin (and the
weblogic plugin, which uses the same code) when running it on a big
applications. As an example: generating the ejb jar for an
application with 200 EJB's takes about 25 minutes on a recent PC
(fast disk, no virus scanning etc).
Now, I don't think the problem is actually in this plugin because
most time seems to be spend reading classes from disk.
Example: in a construct like the following
<j:forEach var="class" items="${ejbUtil.getCMPBeans(metadata)}">
<weblogic-rdbms-bean>
<ejb-name>${ejbUtil.getEjbName(class)}</ejb-name>
...
</j:forEach>
The actual call to the getCMPBeans method (which returns 150 results)
is very fast, but after the return statement it takes about 3 minutes
before the getEjbName method is called the first time. I don't know
what's going on in between but looking at some snapshots of the
thread dump I see a lot threads like the ones below (notice the locks).
Any idea what might be going on?
Regards,
Ive
