如上图DataSourceService的源码，当DataSource为本地实例时，异步接口(含<b>AsyncHandler</b>参数或返回类型为<b>CompletableFuture</b>)与同步接口执行流程相同。当DataSource为远程模式时，调用异步接口时，通信接口发到远程服务器时AsyncHandler参数的值传<b>null</b>，返回数据后再调用本地的AsyncHandler参数值执行。<br/>

异步调用方式是提高服务并发性的有效手段，特别是在远程模式Service比较多的情况下效果更明显。以HTTP服务为例，在Tomcat刚刚改版成NIO的时候，网上随处可见都是大谈NIO性能比BIO多好，认为BIO与NIO的不同，是BIO往往会引入多线程，每个连接一个单独的线程；NIO则是使用单线程或者只使用少量的多线程，每个连接共用一个线程。而事实上呢，通常还是通过增加线程数来提高并发量。为什么NIO作用不大呢， 因为一个HTTP动态请求耗时最多是业务逻辑层，特别是操作数据库，IO操作的耗时比重小得多，只有在静态资源请求这种纯IO操作才能体现NIO、AIO(NIO.2)的优势。举例一个简单的数据查询请求，采用BIO方式耗时（为了方便比较将所耗时间扩大几倍）如下: <br>
|
||||
1、服务器TCP连接开始到进入HttpServlet，耗时 10ms <br>
|
||||
2、用户态判断和参数验证， 耗时 10ms <br>
