no ja jsem mezitim vygoogloval tento dokument

a tam pisi:

To answer the question which system is able to support packet monitoring best we
present a methodology for evaluating the performance impact of various
system components.
We find that AMD Opteron systems outperform Intel Xeon ones and that
FreeBSD outperforms Linux. While multi-processor systems offer a lot,
the benefit
of adding Hyper-Threading and multi-core is small. Moreover, it
appears that for the
task of packet capture the 64-bit OS versions are not quite ready yet.
The newer systems
clearly outperform the older ones and can even capture full packet
traces to disk as
long as the data rate is less than 600 to 700 Mbit/s. All in all,
multi-processor Opteron
systems with FreeBSD clearly outperformed all other systems.
