Tuning is a very interesting topic in the field of Software Engineering. Everybody can agree that it’s important but I have rarely seen people actually doing it. This can be especially true when people have spare computational resources to spend, or if they are following these mantras: “the load won’t reach at this point” or “let the cloud scale it.”
The goal of this post is to share some insights regarding tuning an Apache Camel application deployed into Spring Boot. This is not an ultimate guide for tuning and performance tests in Spring Boot applications, but more of an experience sharing during a tuning process.
When talking about tuning and performance tests, one thing that needs to be clear is the requirements, or what do you want to achieve by tuning an application. For example, one could say that with the computational resources they have, they aim for a 10% increase of requests the application can handle.
