Solr 6.0.0 - SolrCloud java example
<p>I have solr installed on my localhost.</p>

<p>I started <strong>standard solr cloud example</strong> with embedded zookeepr.</p>

<p>collection: gettingstarted
shards: 2
replication : 2</p>

<p><strong>500 records/docs to process time took 115 seconds[localhost tetsing] - 
why is this taking this much time to process just 500 records.
is there a way to improve this to some millisecs/nanosecs</strong></p>

<p>NOTE:</p>

<p>I have tested the same on remote machine solr instance, localhost having data index on remote solr [inside java commented]</p>

<p>I started <strong>my solr myCloudData collection</strong> with Ensemble with single zookeepr.</p>

<p><strong>2 solr nodes,
1 Ensemble zookeeper standalone</strong></p>

<p>collection: myCloudData,
shards: 2,
replication : 2</p>
