I have 2 servers each has 4 cpus and each cpu has 4 cores and the servers have 16gb RAM. I receive every hour 2 8gb files and 2 3gb files. What are the best number of shards and pipelines workers and batch size and JVM heap size basically what should I configure to make the best index speed for these files.

OK. Then I would recommend you review and follow [these guidelines](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/tune-for-indexing-speed.html). Use as few shards as possible and consider using [the rollover index API](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/indices-rollover-index.html) to target a specific shard size.

I would recommend using the defaults as they are quite good.
