Noble Paul commented on SOLR-14636:
-----------------------------------

The next step has to be proper benchmarks. We should be able to capture the 
numbers on

* query/index performance
* memory usage
* garbage collected
* threads used
* time to restart a node/time to do  a rolling restart of the entire cluster
* instabilities like loss of leader/overseer/ZK disconnect etc

There are so many aspects of Solr that we need to be able to measure and report 
before we can prevent people from committing code that makes things worse. 

> Provide a reference implementation for SolrCloud that is stable and fast.
