Performance Problem with WCF proxy

[Former Member]

I communication with SAP XI and Microsoft BizTalk from a .NET 3.0 WCF proxy. I receive about 5 MB of data. When I use a .NET 2.0 generated proxy (Visual Studio) the calls are quite fast and take nearly the same time. If I use a WCF (.NET 3.0) proxy the communication with BizTalk is very fast, but with XI it takes extremely long.

What's the reason for that? Does the WCF proxy parse and validate the message? (5 MB are quite much..., with a few KB I don't have this problem) How can I deactivate the validation?

thanks in advance

Hi Thomas,

not sure what you mean with deactivate validation. have you check with WCF Performance Counters where the problem can be? For more information about performance countes see http://blogs.msdn.com/sonuarora/. Let me now what the counters say, mazbe I'm able to help you then with more details.
