             Summary: camel-core: type converter performs slowly due to exception-based flow control
                 Key: CAMEL-19398
                 URL: https://issues.apache.org/jira/browse/CAMEL-19398
             Project: Camel
          Issue Type: Task
          Components: camel-core
            Reporter: Otavio Rodolfo Piske
            Assignee: Otavio Rodolfo Piske

It looks like, when consuming data of different types, our type converters perform extremely slowly. For instance, in a test sending data of different types (Strings, Integers, Beans, etc) in a machine that easily routes 800k exchanges per sec, with a CBR, it decreases to as much as 49k exchanges/sec. 

Analyzing the frame graphs for this (attached) we can see that there is a significant amount of time spent dealing with handling exceptions. 

Camel's ability to use the processing power available in the machine seems to be severely affected by this:
