Hi Yes it is solrCloud, we saw the same behavior with 1,2 and 4 shards. each shard has 3 replicas.
Each bulk contains 300 docs. We get approximately 800 docs inserted in a second. ~6000 docs are being sent in an iteration by all loading threads. we have 20 threads, each sending bulks of 300 docs. The loaders are waiting for the response, which gets back after ~10 seconds for a loader. Thanks! -- View this message in context: http://lucene.472066.n3.nabble.com/slow-indexing-when-keys-are-verious-tp4327681p4327714.html Sent from the Solr - User mailing list archive at Nabble.com.
