I'm sorry to post this as an answer but I don't have enough score to comment.

If you think it's a GC related issue I'd change it for the Garbage 1 Collector –XX:+UseG1GC

I found this brief explanation about it: http://blog.takipi.com/garbage-collectors-serial-vs-parallel-vs-cms-vs-the-g1-and-whats-new-in-java-8/

Can you run your software under profiling? Try to use the jprofiler, VisualVM or even the netbeans profiler. It may help you a lot.

I noticed that you have your own encapsulation of a vector and matrix. Maybe your are spending a lot more memory than necessary with that too. But I don't think that is the problem.

Sorry again about not contributing as a comment. (It would be more appropriate)
