We have learned that the recent improvements with the JVM technology , intelligent distributed in-memory data storage technology and an optimized in-memory map-reduce technology GigaSpaces XAP provides you can get a deterministic single digit millisecond and sub-millisecond latency without "competing" with the JVM garbage collection and manage offheap data. In many cases reading data from GigaSpaces XAP in-memory data-grid does not involve any serialization or network calls. This avoid any garbage creation and garbage collection which makes Offheap memory irrelevant.

I suggest you review the following: http://blog.gigaspaces.com/possible-impossibility-the-race-to-zero-latency
This shows some results you will find interesting. No Offheap memory approach may deliver such deterministic performance across large data sets and complex applications.
