Is that 3 (each running a primary and a replica shard) or 6 instances? > documents: 120M total > zookeeper: 5 external t1.micros If your facet fields has many unique values and if you have many concurrent requests, then memory usage will be high. But by the looks of it, I guess that the facets fields has relatively few values? Still, if you have many concurrent queries, you might consider using a queue in front of your SolrCloud instead of just starting new requests, in order to set an effective limit on heap usage. - Toke Eskildsen, State and University Library, Denmark
