Is there a quicker way to initialise a BigQuery client?

Question

Using the recommended way to initialise a BigQuery client from the google documentation at Quickstart: Using Client Libraries takes 15 seconds to complete. This seems very slow - is there a quicker way?

import com.google.cloud.bigquery.BigQuery;
import com.google.cloud.bigquery.BigQueryOptions;

public class Test {

  public static void main(String... args) throws Exception {

    long nanotime = System.nanoTime();
    BigQueryOptions x = BigQueryOptions.getDefaultInstance();
    System.out.println("getDefaultInstance " +
                                  (System.nanoTime()-nanotime));
    nanotime = System.nanoTime();
    BigQuery bigquery = x.getService();
    System.out.println("getService " + (System.nanoTime()-nanotime));
  }
}

Output:

getDefaultInstance 15453574055
getService 34049521

The problem is somehow related to the network configuration on the virtual machine. Changing the network settings from "Share with my Mac" to "Bridged Networking" solved the issue (see image below). It now takes 0.6 secs to initialise.
