----------------------------------------------
Comparing the throughput logs:
This is what is can process without the CBR:
{code:java}
2023-05-15 12:30:22,975 [INFO ] Remaining: 97.65825% (50288782 of 2147483646) -
2097194864 messages to finish
2023-05-15 12:30:22,975 [INFO ] Current rate: 816588.600000 exchanges/sec
{code}
This is what it is processing w/ the CBR when consuming data of different
types:

> 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:
> {noformat}
> 39132464047 instructions # 0.80 insn per cycle
> {noformat}
