> Project: Hadoop HBase
> Issue Type: Bug
> Reporter: ryan rawson
>
> HBase wants to have large heaps - store lots of cached objects to make things
> faster in RAM.
> But Java garbage collection wants to touch every object in heap.
> How does this work at 3gb heaps? 6gb heaps? The more ram we can use in
> HBase the better performance we can get. If java GC holds us back, we might
> need to do something else.
