Hi We have found a few spots to optimize the camel-core source code for thread contention and something else.
You can use a profile tool such as YourKit which is excellent at identifying spots and visualizing what goes on in the JVM. We have used it in the past to optimise stuff. However recently Luca asked about making Camel startup faster: https://issues.apache.org/jira/browse/CAMEL-11321 And although fast startup is not excatly the same as runtime performance then they are still related. A profile can help identify places for improvements. I have pushed a sample project at https://github.com/davsclaus/camel-profile-sample You can then run this via mvn spring-boot:run And then attach YourKit profiler. However if you use IDEA then you can start YourKit, then from YourKit you can choose Integrate with IDE ... and then chose IDEA and then say ok even if IDEA is also running. In IDEA you should see a YourKit icon if you right-click on the SampleCamelApplication to run this application, then you can chose that to profile, and it run the app with profiler. You then switch to YourKit and you should start see data. To check for thread contention, then select the "Monitor Usage" tab, and then click the gear button with the play icon "Start Monitor Profile" which then starts capture data. For YourKit you can request a trial license that works for 2 weeks. -- Claus Ibsen ----------------- http://davsclaus.com @davsclaus Camel in Action 2: https://www.manning.com/ibsen2
