Need to backport to Camel 2.11 branch when created.
Fabien, thanks for reporting.
> Camel 2.10 performance regression with added statistics in
> BaseTypeConverterRegistry
> ------------------------------------------------------------------------------------

> Key: CAMEL-6264
> URL: https://issues.apache.org/jira/browse/CAMEL-6264
> Project: Camel
> Issue Type: Improvement
> Components: camel-core
> Affects Versions: 2.10.3
> Reporter: Fabien Chaillou
> Assignee: Claus Ibsen
> Labels: performance
>
> We updated one of our applications from camel 2.7.3 to camel 2.10.3.
> We have a camel route that takes its input from a servlet and we saw a 10%
> performance drop after the update.
> With more tests using yourkit, it appears that we are spending a lot more
> time in BaseTypeConverterRegistry#convertTo method than we used to (from 10ms
> to 3200ms in a test case).
> The only difference between the two version is the added statistics and the
> AtomicLong that must cause contention on our route that uses multiple threads
> behind a seda.
> To improve the issue on our side, we worked-around to avoid having a type
> converter in our hotspots (Which was mainly the
> DefaultHttpBinding#writeResponse from camel-http), but i think a solution
> should be find (maybe make these statistics optionnal).
> Regards,
> Fabien
