    Camel Tracer impedes performance.

      Hi,

       

      I noticed that extending the camel tracer to log exchange data into the database impedes performance on the ESB.

       

      I followed the example in the camel samples, where I defined a direct endpoint

       

       

       

      What I did was to create a custom bean that logs this tracemessage to database. I assume the process of calling this route is off the main route (meaning I assume its like an interceptor and should not in any way slow down the time it takes to travel from one node to another). But it seems it does in reality. As whenever I turn of the custom trace, it takes considerable  less time to complete a transaction and when its on, it takes more time.

       

      A background to this problem that might be helpful is the fact that, exchange message body type is a bean (and not string or xml). I noticed each time its going from one node to another, it implicitly tries to convert from bean to String, before handling the message to the direct endpoint. (May be its just my imagination)

       

      It is also noteworthy that the main route uses vm and the preferred endpoint uri while the log interfaces uses the direct uri.

       

      Is there another way, I can efficiently do this?
