kafka consumer连接时，需要20秒的时间建立连接，正常么？

如果不正常，应该怎么优化？
这是我的代码

private ConsumerConnector createConsumer() {
        Properties properties = new Properties();

        properties.put("zookeeper.connect", "192.168.1.1:2188");
        properties.put("group.id", "1");
        //properties.put("serializer.class","kafka.serializer.StringEncoder");
        properties.put("serializer.class", "com.util.ObjectDecoder");

        // properties.put("auto.commit.enable", "false");
        properties.put("zookeeper.session.timeout.ms", "15000");
        // 指定多久消费者更新offset到zookeeper中
        // properties.put("zookeeper.sync.time.ms", "2000");

        // 必须要加，如果要读旧数据
        properties.put("auto.offset.reset", "smallest");
        // properties.put("auto.offset.reset", "largest");
        return Consumer.createJavaConsumerConnector(new ConsumerConfig(
                properties));
    }
