# Re-use the client object across multiple threads
<a name="best-practices-gremlin-java-reuse"></a>

Re-use the same client (or `GraphTraversalSource`) object across multiple threads. That is, create a shared instance of a `org.apache.tinkerpop.gremlin.driver.Client` class in your application rather than doing so in every thread. The `Client` object is thread safe, and the overhead of initializing it is considerable.

This also applies to `GraphTraversalSource`, which creates a `Client` object internally. For example, the following code causes a new `Client` object to be instantiated:

```
import static org.apache.tinkerpop.gremlin.process.traversal.AnonymousTraversalSource.traversal; 

  /////

GraphTraversalSource traversal = traversal()
                                   .withRemote(DriverRemoteConnection.using(cluster));
```
