In some cases, a wrapper on the remote side might improve performance by encapsulating multiple calls on the remote end into a single remote call.
在某些情况下，远端的封装器可以通过将远端的多个调用封装成一个远程调用来提高性能。
Wrapper services on the remote side of the call are another way to reduce the number of remote calls.
远端封装器服务的调用是减少远程调用数量的另一种方法。
