Log:
JCR-1678: Bad performance in ChildAxisQuery.SimpleChildrenCalculator.getHits()
Problem description
Using a dataset with 20k users, the Calendar home page takes 160s to display the first
time, and 3/4s later.
After 1h (JCR Cache eviction), it takes also 160s to display.
The problem doesn't occur much with 10k users (7s to display).
Fix description
* Avoid invoking getChildNodesData() by storing some needed information in lucene index.
Need to re-index data to ensure that new changes will work.
