Performance issue: integrating WinForm app with legacy COM DLLs


steve clark

We've noticed that invocations of legacy C++ COM DLLs from .NET (Managed C++
or C#) desktop applications is quite a bit slower than the same calls from
good old native C++.

Does anybody have specific information about why this would be the case?
How about performance numbers, benchmarks, etc? Any suggestions to speed up
the connection between new .NET code and legacy C++?

Thanks for your help -
