disabling the intranet interface, using ipf -D lan2 in this example,
each packet is processed only once in each direction (2 and 7). Do not
disable any interface on an end system.
2. If your system has multiple CPUs and LAN cards, be sure traffic is
divided evenly between the CPUs. Interrupt migration and PerfView
utilities can be used to determine that traffic is spread evenly
between CPUs.
3. Dedicate a CPU to each LAN card, if possible. Avoid configuring one
CPU to share an application and a LAN, especially if the application
is data or computationally intensive. Use the HP-UX Processor Set
(PSET) utility to separate applications and LAN processing.
4. If you are configuring an intermediate system, dedicate that system
to HP-UX IPFilter. Do not share the system with other standalone
applications.
