In our previous chapter we have talked about the JVM memory configuration: when to use the defaults and when it might be necessary to fine tune the settings. We also touched on potential side effects of manual tuning and how it can sometimes backfire, for example, forcing the Garbage Collector (GC) to work harder.

In the second part of this series we are taking a look at the different Garbage Collectors available, which is the best for a specific use case, and when it’s useful to switch to a different implementation.
