Any Performance overhead if the application has more 5000 COM objects?

We do industrial automation application and we need to use VC++ application. As part of that we need windows controls which shall be developed in Visual Basic 6.0.

When we run the application with tabbed interfaces, we have approximately 5000 COM objects toge开发者_如何学Gother.

COM object count is expected to grow.

Are are any performance overhead based on usage COM components count within the application?

so far, I don't observe any performance issue.

No, IE8 does not seem to suffer from having scripts referencing many elements at the same time. I think you need to look elsewhere for performance gain.
