Elasticsearch client: speed up client creation

I am developing integration tests with elasticsearch. At the beginning I instantiate the client like this:

Settings settings = Settings.EMPTY;
Client client = new PreBuiltTransportClient(settings)
                .addTransportAddress(new TransportAddress(InetAddress.getByName("localhost", "9300"));

The elasticsearch server is embedded into a docker container, with following environment variables:

- cluster.name=elasticsearch
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
- xpack.security.enabled=false
- xpack.monitoring.enabled=false
- xpack.graph.enabled=false
- xpack.watcher.enabled=false

At each test run, it takes up to 20s just for client creation.

Is there anyway to speed it up? Thx.

By default, Elasticsearch uses two ports to listen to external TCP traffic;

Port 9200 is used for all API calls over HTTP. This includes search and aggregations, monitoring, and anything else that uses a HTTP request. All client libraries will use this port to talk to Elasticsearch Port 9300 is a custom binary protocol used for communications between nodes in a cluster. For things like cluster updates, master elections, nodes joining/leaving, shard allocation
