Hi Emir, We doesn't use routing.
Servers is already balanced and the number of documents on each shard are approximately the same. Nothing running on the servers except Solr and ZooKeeper. I initialized the client as String zkHost = "192.168.1.89:2181,192.168.1.99:2181"; CloudSolrClient solrCloud = new CloudSolrClient.Builder() .withZkHost(zkHost) .build(); solrCloud.setIdField("document_id"); solrCloud.setDefaultCollection(collection); solrCloud.setRequestWriter(new BinaryRequestWriter()); And the documents are approximately the same size. I Used 10 threads with 10 SolrClients to send data to solr and every thread send a batch of 1000 documents every time.
