> Java BB.allocateDirect() will allocate native memory out of the JVM and will
> help reducing the GC pressure in the JVM with a large Cache.
> From some of the basic tests it shows around 50% improvement than doing a
> normal Object cache.
> In addition this patch provide the users an option to choose
> BB.allocateDirect or store everything in the heap.
