I have a elasticsearch cluster I am restoring to in AWS on ec2 instances.
Over the first 30 minutes or so of the restoration, the data throughput was over 500mbps but as the recovery was finishing through more and more shards it started slowing down. Near the end (last 10% of shards) It has slowed to under 50mbps. I noticed this when I was snapshotting as well.
I would like it to progress at the same pace throughout. Is there any reason why it slows down as it nears the end?
