[jira] [Commented] (CAMEL-17019) Performance difference between camel-xslt 2.24.2 & 3.11.1

Daniel Kulp commented on CAMEL-17019:
-------------------------------------

I don't think this is an issue in Camel but more of an issue with the XSLT transform engine in the JDK.  If you run with 3.11.1 and JDK8 (the xslt component in Camel 3.11 still works with Java8 for now), you see a similar performance difference which implies it's JDK related, not Camel.    My gut feeling is all the "Secure Processing" stuff add to the JDK for XML processing/parsing/etc... has caused a bit of a performance degradation to increase security.     I'm not 100% sure on that yet, but it does look like this isn't strictly a Camel issue.

> Hello,
> during some performances tests, we noticed a difference between camel-xslt 2.24.2 & 3.11.1.
> Here is a simplified repo to reproduce: https://github.com/jgreffe/camel-perf-xslt-test
> Please execute:
> - using JDK8: {{mvn clean test -Dcamel.test=2.24.2}}
> - using JDK11: {{mvn clean test -Dcamel.test=3.11.1}}
> We have these results:
> {code}
