> I see, so network traffic is the issue. yup as you can see, every packet is check against your rule set... assuming you have 1000 rules and each rule took 1.5 microseconds to check a packet... it took 1.5 milliseconds to process those 1000 rules per packet (1.5 microsecond x 1000)... and it took approximately 666 packets per second (1000 ms/second / 1.5 ms)... each packet constains 1500 bytes (for ethernet's mtu and 1492 for dsl's mtu)... 666 packets times 1500 bytes times 8 bits per byte is equal to 7.99 mbps.. if you have 100 mbps nic.. it will only consumed 7.99 percent of your total bandwidth... that is why overhead is an issue... fooler. -- Philippine Linux Users' Group (PLUG) Mailing List [EMAIL PROTECTED] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
