Hi, To make the questions short, if we run a cluster of ES in a network supporting max speed of 1MBps, do we have a problem? Our network is more closer to 1GB, but lets assume it was 1MB, what would be the issues? If somebody knows what is the speed on EC2 and the commercial clouds? Best ---

Slower network affects node to node communication. So, slower network means slower everything (indexing, since it does replication, searching, since it hits several nodes). You have an option to compress the messages passed between nodes, this can help with slow networks: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/modules/transport.html).
