Funny you should mention this. The topic is addressed to some extent in this newsletter I received this morning:

www.devcity.net/newsletter/archive/devcity/devcity20041010.htm#ni005

>I just found an interesting quote in a coding guidelines documents:
>
>"Remove the Visual Basic reference from your project. Making use of the original Visual Basic functions has been proven to be up to 1000 times slower than the .NET counterparts; you have been warned."
>
>Do you agree with this quote?
>
>Do you have proof of that?
