Can't give any quick links, just an anecdotal. I used a 486SX/33 with
4MB of ram on a cable connection with no noticeable degradation. I was
still averaging 240Kbps before and after the firewall was put up. This
was on a 256Kbps (theoretical) connection. Upload also chugged along
around 120Kbps, same as before. Personally, I would have to see
degradation to believe it since I've personally seen the lack thereof.


He that would make his own liberty secure must guard even his enemy from
oppression: for if he violates this duty, he establishes a precedent
that will reach unto himself.
