s nejvetsi pravdepodobnosti s rychlosti vs Linux nic. Jeden fw jsem
pred par lety programoval a testovat adresy/porty u IP packetu je
trivialni. Pokud je to tak pomale, tak to nebude tim, ze testovaci
algoritmus je pomaly. Bude to s nejvetsi pravdepodobnosti context
switchema nebo zamkama.

Huge performance improvements in the network stack, including:
* In pf, store routing table ID, queue ID etc directly in the
packet header mbuf instead of using mbuf tags (which use malloc'd
memory). This yields a 100% improvement in pf performance.
Pokud je to pravda, tak by se pf timhle melo dostat tak na uroven
ipfw2. Na testovani nebudu mit v nejblizsi dobe cas.
mne taky zaujalo tohle:
OpenBGPD 4.2:
* Include support for Four-octet AS Number Space.
* Allow the use of pkill -HUP bgpd to reload the config.
