hi, I make a simulation of a real time application. For this project I search an average execution time of netfilter (for send or receive a packet). Any idea? Just an approximation of this time? What the impact of the packet size? Do not include Ethernet card access, or specify it. In addition, I search an average execution time of TCP stack and UDP stack ... to process a packet. Do you know where I can found it please ? Thanks, Guillaume.
