I am using ES to ingest flow data from other application, but I found that the ES speed isn't high enough, so sometimes it would drop flow. How can I change the setting of ES performance ? I have seen the elasticsearch.yml, jvm.options and log4j2.properties, but there seems no setting about ES performance. Thanks a lot. ---

What does your collection pipeline look like? What does your Elasticsearch cluster look like, e.g. Elasticsearch version, number of nodes, number of CPU cores, type of storage and heap size? ---

I think it's the same thread as you already opened at > [@Tuning the ES performance](https://discuss.elastic.co/t/tuning-the-es-performance/105832): > > I am using ES to ingest flow data from other application, but I found that the speed isn't high enough, so sometimes it would drop flow.

As it seems you already have another thread open, I suggest we continue the discussion there. Please do not open multiple threads for the same issue. ---
