Well I'm afraid that is simply not possible because of the different network
environments. It depends very much on your clients and servers. Even on if you
use Apache or IIS. Don't forget that the greatest impact on the Snort
performance is still depending on how many rules you have. And that is great, at
the end.

You will never be able to say that much traffic == that much Snort. You can't
even predict such things with "simple static webservers" properly, can you?
You simply have to test the things and watch for packet drops and then react.

Regards,

Edin
