While there is an excellent ISA firewall performance best practices white paper over at http://www.microsoft.com/technet/prodtechnol/isa/2...s.mspx there is a bit of a learning curve to understanding how to apply that white paper to an actual deployment and busy network admins and sales staff tend to shy away from that kind of work.
To solve this problem, Microsoft has come up with an ISA firewall sizing calculator. You can find it on the ISA firewall landing page over at www.microsoft.com/isaserver and it’s part of the flash content at the top of the page.
