Hi Will, Thanks for your response. These Solrcloud instances are 8-core machines with a RAM of 24 GB each assigned to tomcat. The Indexer machine starts with -Xmx16g. All these machines are connected to the same switch.
The batch size is 5000 documents and there are 8 threads which adds 5000 document's batch per thread to solrcloud. I have tried with a bigger batch size but that caused OutOfMemory error. I can see the Solr cloud instances are not running out of memory or going low in memory. The CPU utilization is also around 50% on each core. Whereas indexer is using maximum of the assigned memory which is -Xmx16g but is not going out of memory.
