因此，能从异步中获得最多好处的联邦查询是那些其远程查询比较复杂，在返回第一行数据之前需要花费较多时间的查询。
Thus, the federated queries which benefit the most from asynchrony are those whose remote queries are complex and and for which it is time consuming to return the first row.
此外，如果远程查询都是执行大约相同一段时间之后返回第一行数据，那么异步带来的好处就可以实现最大化。
In addition, if the remote operations take approximately the same amount of time to return the first row, then the benefit achieved in enabling asynchrony is maximized.
通过创建简单的实用程序类很容易获得异步远程接口的实例(清单8中的第7 - 13行)。
A simple utility class is created to easily get the instance of the async remote interface (lines 7-13 in Listing 8).
