Please don't mix .NET and OPC-XML. That are technically different
topics. OPC-XML is of course much slower than any other communication.
I'm wondering for 3 years why the OPC Foundation didn't works out a new
standard without DCOM. DCOM is dead since the .NET Framework cames out
in 2002 (2001 the betas).
