I run a small solr cloud cluster (4.5) of 3 nodes, 3 collections with 3 shards each. Total index size per node is about 20GB with about 70M documents.
In regular traffic (27-50 rpm) the performance is ok and response time ranges from 100 to 500ms. But when I start loading (overwriting) 70M documents again via curl + csv, the performance has drastically improved. I see a 6ms response time (screenshot attached). So I am just curious about this, intuitively solr should perform better under low traffic and slow down as traffic goes up. So what is the reason for this? Efficient memory management with more data? -- Thanks, -Utkarsh
