I have 6 machines，and each machine run a solr server, each solr server use RAM 18GB. Total document number is 3.2billion，1.4TB ， my collection‘s replica factor is 1。collection shard number is 60，currently each shard is 20~30GB。 15 fields per document。 Query rate is slow now，maybe 100-500 requests per second.
