Do you really need a 4GB heap with a 2GB young generation? Bigger is not necessarily better when it comes to Java heaps. It does look like you are freeing up 2GB of garbage every 10 seconds, that is a lot of garbage. Some code must be generating that garbage. It also looks like your working set size is around 160MB. I would try setting Xms/x to 900MB and Max/NewSize to 300MB. Or perhaps 1200M/400M. Of course, at the rate your app is generating garbage that will cause GCs to occur more often.
