When I was running as follows: 10mbit network -> pix -> freebsd gateway -> internal network (100mbit) with 100mbit ethernet on the fbsd gateway, 10mbit up to the gateway (there are routers inbetween the pix and the gateway), and 100mbit on the internal network, my connection speed per connection when from about 550k/sec to over 750k/sec with it set, thats a fair bit of a improvement. Also 100mbit -> 100mbit it went from about 4.5meg/sec to about 6meg a second, again, a fair big improvement.
