Reuse the same proxy In many cases, you would want to reuse the same proxy. This has the best performance. It is especially true when you use security features since the initial security negotiation can have high cost.

proxy equals channel. if you look at this blog post, you can see the following code snippet:

ISimpleContract proxy = factory.CreateChannel();
((IClientChannel)proxy).Open();

Furthermore, if you plan to work with sessions, you don't want to establish a new session for each request (by creating a new channel/proxy each time).
