Load Testing Camel Routes

[Matt Raible <ma...@raibledesigns.com>]

Hello all,

I'm getting ready to put a Camel / CXF / Spring Boot application into production. Before I do, I want to load test and verify it has the same throughput as a the IBM Message Broker system it's replacing. Apparently, the old system can only do 6 concurrent connections because of remote database connectivity issues. 

I'd like to write some tests that make simultaneous requests, with different data. Ideally, I could write them to point at the old system and find out when it falls over. Then I could point them at the new system and tune it accordingly. If I need to throttle because of remote connectivity issues, I'd like to know before we go to production. Does JMeter or any Camel-related testing tools allow for this?

Thanks,

Matt

Hi Matt,

I've replaced JMeter with Gatling [1], which has a nice DSL to work with and in my opinion much faster to write tests when compared to JMeter. Having said that, the apache ab tool (cli) [2] is useful for the initial checks. If you have routes that work concurrently, Camel's JMX statistics has proved invaluable to find bottlenecks especially when tuning the optimal number of threads required. A good profiling tool also helps.

Also, if you're using Jetty for CXF, keep an eye on its threading parameters.

Hi Matt!

We are using httpcore-ab [1] to load test our web services. Unfortunately, you cannot change the payload for each test, but it works well for us.
