Many thanks for sharing your experience.  We did not get a lot of  
feedback/comments in the recent months about the performance  
characteristics of Camel 2.0.  We are committed to listening *very*  
carefully to what the community has to say and I encourage you to  
share as much as you can from your test results and any suggestions  
you might have.

We are in the closedown phase of 2.0, we want to make 2.0 much better  
and your voice is important.  We are quite flexible and we'll squeeze  
2.1 improvements in 2.0 whenever possible.  The goal is to not delay  
2.0 unnecessarily.  And obviously we appreciate all the help we can get.

Thanks again,
