["Claus Ibsen (JIRA)" <ji...@apache.org>]

Claus Ibsen updated CAMEL-5675:
-------------------------------

    Attachment: CAMEL-5675.patch

I have attached a patch which has caching on JMX and IntrospectionSupport. 

The most noticeable performance improvements is when JMX is enabled, and if you have large routes.

The big route tests is about cut down from 8s to 4s on startup (looking at the startup time Camel reports itself).

> I am writing unit tests for Camel and found that each unit test was taking up to a second just to create the Camel routes. That's not very long, but we have a large unit test suite that needs to run quickly.
> I did a performance profile and found that most of the time is going to the method org.apache.camel.util.IntrospectionSupport.getProperties(Object, Map, String). That method, then also calls IntrospectionSupport.isSetter(Method), and just running two unit tests I saw isSettter called 2.5 million times!
> It seems to me that a cache per class of the properties would make a huge performance improvement on Camel route building.
