Hi Andriy,  
It might help to disable refresh interval during ingestion and set replicas to 0.  
Of course, in case you don't need to search while importing documents.  
Take a look at my post here as well: [Elasticsearch indexing performance: throttle merging](https://discuss.elastic.co/t/elasticsearch-indexing-performance-throttle-merging/71549/8)
