-### Configuring the client to use a connection pool.
-
-By default oriento uses one socket per server, but it is also possible to use a connection pool.
-You should carefully benchmark this against the default setting for your use case,
-there are scenarios where a connection pool is actually slightly worse for performance than a single connection.
-
-```js
-var server = Oriento({
-  host: 'localhost',
-  port: 2424,
-  username: 'root',
-  password: 'yourpassword',
-  pool: {
-    max: 10 // 1 by default
-  }
-});
-```
