I'm putting this on the net for a friend, hence the two signatures.
Can anyone who replies directly send mail to both of us, else 
a posting will be fine.

I'm using C++ in the VLSI routing domain, where software
has previously been written in a number of languages.
Not much in OOLs however ( as far as I am aware ).

Speed is a very important factor when considering
the advantages and disadvantages of routing algorithms,
and as a result I am interested in the overhead due to 
messaging in OOP when compared to "conventional" programming. 

Does this overhead affect the speed of my software in any 
significant way?

I would appreciate any comments from anyone knowledgable in
this subject matter or even some references on messaging
overhead in OOP.
