> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: mongomk

> Fix For: 1.3.7

>
> By default the cache memory in DocumentNodeStore is distributed in following
> ratio
> * nodeCache - 25%
> * childrenCache - 10%
> * docChildrenCache - 3%
> * diffCache - 5%
> * documentCache - Is given the rest i.e. 57%
> However off late we have found that with persistent cache enabled we can
> lower the cache allocated to Document cache. That would reduce the time spent
> in invalidating cache entries in periodic reads. So far we are using
> following ration in few setup and that is turning out well
> * nodeCachePercentage=35
> * childrenCachePercentage=20
> * diffCachePercentage=30
> * docChildrenCachePercentage=10
> * documentCache - Is given the rest i.e. 5%
> We should use the above distribution by default if the persistent cache is
> found to be enabled
