Justin,
I understand and share your concern. Unfortunately I cannot tell you
since I have no idea what you use.
In our case, we test them with unrealistic loads (all ports running
ttcp) which is much more than a typical user will ever do. Adding such
a filter is quite minimal in our case since our algorithms are pretty
tight.

How much spare processor do a lot of the dial access servers have left on
them? I am somewhat concerned about the amount of processor left on my dial
access servers.
