The garbage collector is a complex piece of machinery that can be difficult to tune. Not surprisingly, many developers dread touching the GC. If you don’t give the GC just a little bit of care, your whole application might be running suboptimal. This blog post shows how we got two production applications to perform better by following simple tuning steps.
Spicing up your app’s performance - a simple recipe for GC tuningCoroutines are a wonderful way of writing asynchronous, non-blocking code in Kotlin. Think of them as lightweight threads, because that’s exactly what they are. Lightweight threads aim to reduce context switching, a relatively expensive operation. Moreover, you can easily suspend and cancel them anytime. Sounds great, right?
Coroutine Gotchas - Bridging the Gap between Coroutine and Non-Coroutine WorldsIf you’re performing web requests with Spring Boot’s WebClient you perhaps, just like us, read that defining the URL of your request should be done using a URI builder
Avoiding memory leaks with Spring Boot WebClientPrevention is better than cure - a fundamental principle of health care that also applies to modern software development. The later a bug surfaces, the more effort it takes to repair. From our own experience we know that this especially applies to performance bugs.

The hyped, happening and happened programming languages and testing frameworks @ bol.com (Part 2)Introduction For me, even after having pushed the deploy button many times, deploying to production keeps being dreadful. Accidentally pushing an unwanted feature that sneaked in somehow is one of the many things I am afraid of. In this...
