[OT?] tcpdump overhead

[Mario Lobo]

Hi there;

Forgive this possible OT (and lame) question.

I am writing a final paper for a PG course and  I need to take precise 
measurements on network performance. I gonna be doing lots of packet dumps 
and I would like to know you guys' opinion on how much of tcpdump overhead 
(if meaningful for these measurements) I should take into account.

If there are any readings on the subject you could point me to...

Thanks
