I setup ES 6.0 Service on AWS using m3.xlarge.elasticsearch, i followed Network Limits (http://docs.aws.amazon.com/elasticsearch-service/latest/developerguide/aes-limits.html).
Bulk insert on my local network is too fast (12 min for 4 millions of document) but too slow on AWS (4 hours for same documents).
I set the replicas to 0 ,refresh_intervall "-1" and other things that said for performance improvement, but no any luck.
