Those aren't facts of a pc user running a software firewall seeing bandwidth degredation..

given the latencies involved with networking and the size of the network pipe via a CPU + bus theres going to be zero slowdown.

If you managed to achieve a full 100Mbs data push from a PC via software firewall to a 100Mbs net card to a local area network, the bus would hardly notice,..

note thats a 100 Mbs per second, hardly a hit at all.. Most routers have an insignicant processing power compared to a PC.

The intel article is for VPN + Firewall, note the phrase

"The addition of VPN to firewalls usually alters performance greatly."

Its a totally different beast, VPN has a lot more going on. The second article says 'affects PC performance' not affects 'network performance'.

of course you can't be bothered looking for facts, they don't exist.

What exactly do you think a hardware firewall is ? its a cut down PC like device, with considerably less CPU power , it runs its "software" from a rom or such instead of a disk, although its pathways are optimized, its because its considerably less powerful than a PC. Most firewalls run on dinky CPU's

A 1000 gallon per minute pump going through a 10 gallon per minute valve, can reduce in effiecieny down to 500 gallons per minute, and the 10 gallon per minute valve will still be delivering maximum throughput.
