Conclusion

With the enormous number of possible applications that one may run on the JVM, coupled with the hundreds of JVM configuration parameters that one may tweak for GC, there are astoundingly many ways in which the GC may impact your application’s performance.

Therefore, there is no real silver bullet approach to tuning the JVM to match the performance goals you have to fulfill. What we have tried to do here is walk you through some common (and not so common) examples to give you a general idea of how problems like these can be approached. Coupled with the tooling overview and with a solid understanding of how the GC works, you have all the chances of successfully tuning garbage collection to boost the performance of your application.
