--------------------------------
Assignee: Freeman Fang
> SourceTransformer should cache DocumentBuilder & TransformerFactory
> -------------------------------------------------------------------
>
> Key: SM-2069
> URL: https://issues.apache.org/jira/browse/SM-2069
> Project: ServiceMix
> Issue Type: Improvement
> Components: servicemix-utils
> Affects Versions: servicemix-utils-1.5.0
> Environment: http://svn.apache.org/repos/asf/servicemix/utils/trunk
> Reporter: Jonathan Anstey
> Assignee: Freeman Fang
> Attachments: cache_docbuilder.patch, cache_docbuilder_test.patch
>
>
> I noticed that when routing between JBI endpoints in Camel like:
> {code}
> from("jbi:endpoint:serviceNamespace:serviceA:endpointA").to("jbi:endpoint:serviceNamespace:serviceB:endpointB");
> {code}
> There is a huge overhead creating new TransformerFactory and DocumentBuilder
> objects. After caching these on a per thread basis I was able to get a test
> case down from 41.583 sec to 18.224 sec.
> To test this, apply the attached patch (cache_docbuilder.patch) to the
> servicemix-utils trunk, and also modify the servicemix-camel component with
> the attached patch (cache_docbuilder_test.patch) and run the following:
> janstey@duffman:/x1/asf/servicemix/components/trunk/engines/servicemix-camel$
> mvn clean test -Dtest=SendFromCamelToJbiThenRouteToAnotherJbiComponentTest
> You may need to up surefire's Xmx as well.
> If someone is going to commit this, please only commit the code in
> cache_docbuilder.patch
